The Convention Crasher is the title of a documentary originally broadcast in the United Kingdom on 25 January 2007 on Channel 4. The one-off documentary followed Justin Lee Collins as he entered the world of celebrity lookalikes and attempted to become one himself before visiting a convention for them.
The show returned on 17 January 2008 for a series with Justin Lee Collins this time crashing three conventions, each on magic, ventriloquism and clowning.
