Colin Farrell has described working on his latest movie project, Seven Psychopaths, as a "wonderful adventure".

The Irish actor is teaming up once again with In Bruges director Martin McDonagh for the crime-based comedy.

Speaking about the movie which is due for release in December, Farrell revealed he was immediately drawn to the script as it is full of surprises and twists.

He said: ''With the Seven Psychopaths script, every now and then you read something and it just jumps off the page, and Seven Psychopaths does that ... and then it slaps you across the face, it gets you by the back of the head and slams you into a table, then it gives you a kick in the arse - it really takes you on a wonderful ride."

The Dublin native added: ''I was delighted to be working with Martin again. I loved the script for Seven Psychopaths.''

Farrell, 36, plays struggling screenwriter Marty, who is trying to write his screenplay Seven Psychopaths. However, he inadvertently becomes entangled in the Los Angeles criminal underworld after his oddball friends kidnap a gangster's beloved Shih Tzu dog to inspire Marty's story.

Talking about his character, Farrell said: ''Marty's having a little bit of a difficulty because he's already found the title and he's fallen in love with the title Seven Psychopaths, but he hasn't come up with any of the psychopaths.

''And he wants the story to be about peace and love, but it's still gotta be about Seven Psychopaths, so he's in the midst of that quandary.''
