for fashion weeks in Paris and New York. Film debut and breakthrough (2012–2018) Penty was originally slated to make her Bollywood debut in 2011 with Imtiaz Ali's Rockstar opposite Ranbir Kapoor, although she rejected the film due to her modelling commitments at the time and was subsequently replaced by Nargis Fakhri. She later signed up for Homi Adajania's Cocktail instead; at Ali's suggestion. Cast alongside Saif Ali Khan and Deepika Padukone, the film received mixed to positive reviews. Penty's portrayal of Meera, a simple Indian girl with traditional values was well received by critics. Taran Adarsh of Bollywood Hungama commented that "Diana, who makes her acting debut, gets to portray a rather difficult character for her debut film. There's a very disarming kind of innocence that she brings to the role and she impresses a great deal." Raja Sen agreed, mentioning that she is "refreshingly natural". Anupama Chopra added that "Diana is saddled with the most colourless character but [...] infuses her role with a quiet poise and holds her own." Her performance earned her nominations for best debut and best supporting actress at numerous Indian award ceremonies, including International Indian Film Academy Award for Best Supporting Actress.

About the break from acting, Penty said: "It wasn't a conscious break. I was taking my time looking to be a part of an interesting story. I didn't want to do anything that came my way." The film earned mixed reviews from critics but was a sleeper hit. Rohit Bhatnagar wrote that Penty "steals the spotlight in every frame", while Anna M. M. Vetticad of Firstpost said: "Penty is brimming with potential [...] but her Happy, despite being the titular protagonist, is the most under-written character." Her sole role in 2017 was that of Gayatri Kashyap, a diligent NGO worker who champions the cause of a band formed by a group of prison inmates, in debutante Ranjit Tiwari's prison film Lucknow Central, which starred
