• Pass on
• Frog noise
• Action film that would complete the five-film set of a certain well-known actor's five-letter movies. Can you spot the unusual letter pattern among the existing four films (at 61, 63, 64, and 68 Across) and then figure out what the remaining film would have to be called to fit the pattern? (The title of the would-be film is a common word whose slang meaning, aptly enough, is "kill" or "die.") The pattern works only if the would-be film comes second in the five-film list.
