 Levin was going to do a film about the Danish resistance for Allen, "The Savage Canary" from a script by John Paxton but it was not made.Instead Levin did two Matt Helm films with Dean Martin for Allen, "Murderers' Row" (1966) and "The Ambushers" (1967).During the making of the latter, a newspaper profile was published which claimed Levin's marriage was in trouble.
