In this chapter discusses at comic performance in television and film. Brett Mills notes that for the success of sitcom as a genre, 'acting clearly plays a significant part in the ways in which comedy is made to make sense' and so the comic performance craft skills that one have developed, along with his/her knowledge of the buttons for provoking laughter, need to be in place. In contemporary British television comedy, the presence of a studio audience is still a vital signifier of intended comic response. The actor David Jason refers to the presence of a studio audience while playing comedy as 'intrusive' and the same sense of discordance can also hold equally true for the viewer, who may feel alienated by what she/he perceives as disproportionate 'live' laughter from the invited studio audience. The illusionist and human psychology exponent Derren Brown can tell all sorts of things about people from what we exude from behind.
