Hugh Laurie auditioned for the role as Dr. Gregory House in his hotel room bathroom in Namibia. He was rehearsing his role for the film The Flight of the Phoenix and claimed that the bathroom was the only place with enough light. He also apologized for his appearance on tape before the audition as he'd just come back from filming. The fact that House has a somewhat scruffy and unkempt look, particularly his constant five o'clock shadow, has been attributed by creator David Shore to Laurie's appearance in this audition tape.
