It's a year since the release of "Happy New Year", and director Farah Khan can only look back at the ensemble-cast movie as her "happiest filmmaking experience" ever.

The action comedy film, starring Shah Rukh Khan, Deepika Padukone, Abhishek Bachchan, Boman Irani, Sonu Sood, Vivaan Shah and Jackie Shroff, revolves around six would-be thieves, who enter a prestigious dance competition as a cover for their larger goal of pulling off a major robbery.

"Happiest filmmaking experience ever," Farah tweeted on Sunday.

Shah Rukh, who is known to be a close friend of the director, has also worked with her in movies like "Main Hoon Na" and "Om Shanti Om".

The "Chennai Express" actor too seemed nostalgic and took to the micro-blogging website Twitter and mentioned that he "missed" the film's cast and crew.

"It's been a year since @HNY released! Miss those goofy times with my Indiawaale! #1YearOfHNY."
