I always thought this episode was overrated. The second murder was one of the most unrealistic in whole series. There is no way he could walk in and out of the theater and projection room without being noticed. I'll take Death Lends a Hand as my favorite episode with Kulp.
As much as I like the other actors, I think Louise Latham's second scene really stands out. I always like that smile she gives when Columbo tells her he believes her by saying "My wife could come up with a better alibi than that."
