Saif Ali Khan's "Happy Ending" has combined some moments in a video where the entire cast and the crew of the film is seen grooving to one of the popular songs of 2014, Pharrell William's "Happy".

The video, which will be shown at the end of the film, begins with Saif saying Kareena Kapoor Khan (who plays a cameo as Saif ex-lover) that they can "still be friends". And in reply his real-life wife shows her middle finger and leaves only to return and starts dancing with him on the popular song.

Saif is later seen making some crazy moves with actress Preity Zinta, who too plays a short role as his ex-girlfriend.

Even the lead actress of the film, Ileana D'Cruz, Kalki Koechlin and actor Govinda are seen dancing to the song. The video also features the movie's crew members dancing with the cast.

"Happy Ending", which also features Ranvir Shorey, is a romantic comedy entertainer scheduled to hit the screens on 21 November. The film co-produced by Saif and Dinesh Vijan under the banner Illuminati Films is written and directed by Krishna DK and Raj Nidimoru.

The comedy film is shot in several foreign locations and a major portion in San Francisco, California. The songs of the film have been garnering good responses from the audiences.

Meanwhile, Saif is also busy shooting for "Phantom" that has Katrina Kaif in the lead actress role. Produced by Sajid Nadiadwala, "Phantom" is a counter-terrorism drama film, where both Saif and the "Bang Bang" actress are supposedly playing secret agents. The film has a series of action sequences and is supposedly based on the 26/11 Mumbai attacks.
