Directed by "Being Cyrus" director Homi Adajania, "Cocktail" features actors Saif Ali Khan, Deepika Padukone and newcomer Diana Penty, in lead roles.
Co-produced by Saif Ali Khan and Dinesh Vijan of Illuminati films, the story is centred around Gautam (Saif), Meera (Diana) and Veronica (Deepika).
Gautam is an incorrigible flirt, while Meera, a pretty girl who wears Indian clothes and exudes Indian values, comes to London from Delhi for a fresh start, and Veronica is a party animal.
As three people living together, they all have a blast - until love happens!
The perfect friendship turns confusing, and love becomes complicated.
Adajania says Imran Khan was his first choice for the film.
"Saif was not the first choice. Imran was supposed to do it but he was not sure if he wanted to do it at that point of a time, " Adajania told.
Actors Dimple Kapadia and Boman Irani feature in supporting roles.
Explaining their presence in the cast, he said: "Dimple and Boman are also there in the film and it is not like they were in 'Being Cyrus' so are part of this film as well. It is not a matter of familiarity but using talented actors who fit the bill."
Actor Randeep Hooda will be seen in a cameo.
The film has already grabbed eyeballs for its ultra-modern styling by designer Anaita Shroff Adajania, and bagged a thumbs-up for its music, composed by Pritam Chakraborty.
Quirky song "Second hand jawaani", with Saif, Deepika and Diana grooving together, has also gained popularity among music lovers.
