She has also continued her stint in music through work as a singer in Indian languages, a career in music direction beginning with her father's productionUnnaipol Oruvan and her own music band and album.
Haasan's first appearance in a feature film was a cameo role as the daughter of Vallabhbhai Patel in the Tamil-Hindi bilingual Hey Ram, based on a murder attempt of Mahatma Gandhi, directed by her father Kamal Haasan. After rejecting prominent film offers, most notably the lead role in Venkat Prabhu's Saroja, reports suggested in late 2007 that Haasan was set to make her actual acting debut in 2008 with a film opposite Madhavan directed by Nishikanth Kamat. Despite Madhavan admitting that the news "was premature", she eventually did sign up to the film, which was titled Endrendrum Punnagai, only to be stalled prior to production.
Haasan eventually signed up to feature in Soham Shah's Hindi film Luck opposite Imran Khan in July 2008, and shot for the film for nearly a year. Imran Khan, her childhood friend, had recommended her name to the director and Haasan signed on after listening to the entire script and accepted to play a dual role in the action film. Shruti took part in action scenes during filming, while she also worked out to get a toned body for a sequence in which she appears in a bikini in the film.The film opened in July 2009 to unanimously poor reviews from critics and took a poor opening at the box office, with critics stating that she "deserved a better launch vehicle". Reviewers were critical of her performance with Rajeev Masand of IBN stating that she delivers "dialogues with deadpan expressions", while another critic added that she is perhaps"synthetic and fails to impress". Haasan then went on to appear alongiside Blaaze in the promotional videos for Unnaipol Oruvanand Eenadu, the bilingual films starring her father, which she had composed the music for. She made a further appearance in a promotional video for the horror film Hisss starring Mallika Sherawat, where she had also sung a song composed byDave Kushner.
She made her Telugu debut in January 2011, acting opposite Siddharth in the fantasy adventure film Anaganaga O Dheerudu directed by Prakash Kovelamudison of director K. Raghavendra Rao. The film, co-produced by Walt Disney Pictures, saw Shruti play a gypsy woman whose life coincides with a task that a blind swordsman, played by Siddharth. The film opened to positive reviews, with her performance being praised with a critic noting "Shruti looks quite attractive and makes a wonderful screen presence," while a reviewer from Rediff.com wrote that she "looks beautiful and has a mystical aura about her". The film however became a commercial failure at the box office, and the film failed to capitulate on a hefty promotional campaign that had been undertaken.[clarification needed] Her second Hindi feature film, Madhur Bhandarkar's romantic comedy Dil Toh Baccha Hai Ji, saw her appear in an extended guest appearance alongside an ensemble cast of Emraan Hashmi, Ajay Devgn andShazahn Padamsee. The film portrayed her as Nikki Narang, the step-daughter of an ex Miss India model, with Hashmi's character falling for both mother and daughter. Shruti's performance gained poor responses from critics with a reviewer citing that her character has been "reduced to post-interval surfacing, last-ditch glamour" whilst another labelled hers as "so fake that she offers only disappointment"; however the film went on to become a commercial success at the box office. In mid-2010, Shruti was signed by A. R. Murugadoss to star opposite Suriya in his next film 7aum Arivu, and the film's shoot began in June later that year. The director signed after he felt she looked the part of the scientist, mentioning that she seemed "intelligent and beautiful". Shruti played Subha Srinivasan, a young scientist in the film, who hopes to re-activate the genes of 5th century Buddhist monk Bodhidharma and her performance in the film won appreciation from critics. The film opened to mixed reviews, but became commercially successful. A critic from The Hindu noted "rarely is a heroine given near-equal footing in Tamil films," describing her as "ravishing but that she ought to work harder on spontaneity, and fine-tune her Tamil accent", but concluded "the point is the actor shows promise". Her next Telugurelease was Oh My Friend, a romantic comedy film alongside Siddharth again, which also co-starred Hansika Motwani andNavdeep. The film told the story of childhood friends and that of their platonic friendship that went on in their adulthood as well and for the role Shruti Haasan went on to learn the dance of Kuchipudi. The film opened to average reviews with several critics claiming the film evoked a sense of "déjà vu", though a reviewer noted "Shruti, on her part displays the same conviction."
Shruti Haasan was next seen in Aishwarya Dhanush's directorial debut 3, a romantic drama film co-starring Dhanush. Aishwarya revealed that she had written the script with Shruti Haasan in mind but date problems meant that the film began its shoot with Amala Paul instead. However in a turn of events, Shruti was re-signed to play the character of Janani, and the film gained much hype prior to release due to the collaboration of herself and Aishwarya, being the daughters of the two leading contemporary Tamil actors Kamal Haasan and Rajinikanth as did the success of the song Why This Kolaveri Di?. The film opened in March 2012 to positive reviews with a critic noting "Shruti Hassan has come a long way," though the film only garnered average returns at the box office. Her second release in 2012 was Harish Shankar's Telugu film Gabbar Singh, a remake of the 2010 Hindi film Dabangg, with the version featuring her alongside Pawan Kalyan. Shruti had signed the film in November 2011 replacing Ileana D'Cruz who had opted out, and played the role of Bhagyalakshmi, a village girl, which had been essayed by Sonakshi Sinha in the original version. The film went on to become a major commercial success at the box office and brought in more film offers for Haasan. Critics also gave her performance a favourable verdict citing that she "justifies her role" and "though she didn't have much of a role, she has left her mark."

Haasan mainly received positive reviews for her performance, with critics noting that she "provides the fun in the film with glamor and verve". Later that year, Haasan made a comeback to Hindi films, with Prabhu Deva'sRamaiya Vastavaiya and Nikhil Advani's D-Day. The films emerged as moderate successes and Haasan received generally positive reviews for her performances.

Along with the rest of the film, Haasan received positive reviews for her performance, with one critic noting that she "plays her part well and looks glamorous".

Shruti sang the bilingual versions of the title theme, Rama Rama with her father, in Hindi and in Tamilfor the movie Hey Ram.
