This is quite a corny Marvel, a fairly amusing one though.
Johnny Blaze is a stunt motorcyclist who sells his soul to the devil so that the latter can cure his father of cancer. The devil plays a trick on Johnny. Also it takes a while before he comes pick up Johnny for his task: he will be a contract killer.
In a very over-the-top way, Johnny turns into a burning motor driving hitman during the night. In the meantime he runs into the love of his youth.
Not without reason Nicholas Cage was hired to play Johnny Blaze. I find some of the other actors less convincing for their parts. Overall the film is mostly cheap entertainment, but somewhat entertaining.
