Seth Rogen's forthcoming Christmas movie has been renamed 'The Night Before'.

The 33-year-old actor stars alongside Joseph Gordon-Levitt, 34 and 'Avengers' actor Anthony Mackie, 36, in the festive comedy and film bosses have decided to scrap the previous title 'X-Mas' at the last minute.

Filming for the project began last year and Seth teased on social media at the time that the project was called 'X-Mas', however it wasn't confirmed until an announcement was made at this year's CinemaCon.

And now, an even later announcement by filmmakers Columbia Pictures - along with the release of the movie's trailer - has stated that it will be called 'The Night Before', according to Collider.com.

The comedy - which reunites '50/50' director Jonathan Levine with Seth and Joseph - is due to be released in November and follows three childhood friends Isaac (Rogen), Chris (Mackie) and Ethan (Gordon-Levitt), who reunite in New York City to party for one last Christmas Eve together before they get too old for the tradition.

Seth is a busy man at the moment, as he is also throwing a Bar Mitzvah for his and Joseph's friend James Franco, in Los Angeles on October 17, 2015 to help raise funds for he and his wife Lauren Miller Rogen's organisation Hilarity for Charity.
