 McGoohan was impressed by his acting skills and perfectionism (to prepare the duel scene, both actors practised quick-draw assiduously).As a result, McGoohan wrote for Kanner the role of Number Forty-eight, who is made to stand trial as the representative of rebellious youth in "Fall Out", the final episode of the series.Additionally, Kanner gave an uncredited performance as the photographer in the comic-book episode "The Girl Who Was Death", in which he performed a number of stunts on a roller coaster.
