Justin Lee Collins investigates the strange world of celebrity impersonators and tribute artists by crashing one of the industry’s biggest conventions in Orlando, Florida.

For one weekend only, Justin’s mission is to convince the professionals he is a genuine tribute artist. But who will transform himself into… Barry Gibb, Tom Jones… Alison Moyet?

Along the way Justin meets the people for whom this is a full-time job, including a man whose similarity to George Bush has turned him into the highest paid look-alike artist in the world.

The Convention Crasher will air on Channel 4 on Thursday 25 January 2007
