The All Together is a 2007 comedy film written and directed by Gavin Claxton and starring Martin Freeman, Corey Johnson, Velibor Topic and Danny Dyer.
[1][2] Frustrated TV producer Chris is a self-opinionated wannabe screenwriter (with a particular dislike of British films featuring quirky secondary characters and plastic gangsters) who is forced to leave his unreliable flatmate Bob in charge of showing a series of estate agents around the house he is trying to sell.
Worried by Bob's habit of spending all day "working" in the basement playing loud music, Chris asks his friend to listen out for the door bell and show anyone who comes calling inside.
Bob has indeed, allowed anyone inside, including a couple of archetypal movie-style gangsters – an incompetent young Brit played by Danny Dyer and an incontinent American.
That evening, Chris is surprised to return home and find his flatmate, four estate agents, two Jehovah's Witnesses and a terrified children's entertainer being held hostage by a couple of characters straight out of a British gangster film.
