Man mistakenly believes that he is in a TV show [closed]

Question

This is a comedy - lead character is male, and I believe it was set in Britain. There exists a TV show (in the fictional world of the movie) where people can set up their friends. The "victim" responds to some "random" event which sets off a scripted series of events which are filmed and designed to provide excitement.

From what I remember: the man answers a phone call, breaks up a fight between a couple in a home, and somehow becomes involved with real criminals whilst believing it is all scripted and part of the show.

I believe this movie was released in the 1990's.

Answer 1

Sounds like The Man Who Knew Too Little (1997), starring Bill Murray:

An American gets a ticket for an audience participation game in London, then gets involved in a case of mistaken identity. As an international plot unravels around him, he thinks it's all part of the act.
