Yes - Payback & Point Blank (1967) are very similar. But there is a very good reason for that. Both films are based on the novel 'The Hunter' by Richard Stark, a pseudonym for Donald E Westlake.
The films share several character names such as Brewster, Carter, Stegman and Fairfax and similar plots. In both cases the anti-hero Porter (or Walker) is trying to recover a sum of money after being double-crossed.
Now, I am a huge fan of Point Blank. It takes a relatively simple plot and makes a bit of cinematic poetry out of it. And if I was forced to compare Lee Marvin and Mel Gibson's performances, then I'm sorry but Gibson would lose big time. However, Payback is a much better film than I thought it would be. There are sufficient differences to make the story interesting and though it is told in a much more straightforward and, dare I say, 'safe' way than Point Blank, it is a very well made film and tells a compelling story well. And it's nice to see Gibson return to a somewhat morally ambiguous character a la Mad Max.
