TCM is airing this right now!
The TV listing has it as "Door-to-Door Maniac", but the opening title is "Five Minutes to Live". It's one of TCM's "Underground" films and happens to be one I hadn't heard of before.
It's fun seeing a younger Vic Tayback and Johnny Cash in a solid role. I'm also looking forward to seeing Ronnie Howard in only his second film role though he'd been acting since 1956.
I see that the lady in jeopardy is played by Cay Forrester, who also wrote the screenplay!
