Early in the movie "A Mighty Wind", there is a montage of archival folk musician footage combined with fake archival footage of the fake folk bands in the film. One of the real snippets of footage, just after 1 minute into the film, shows a couple of young guys playing banjos. It appears to be the late 1950s or early 1960s:
Is it me, or does the guy in the middle look like Steve Martin? It's so hard to tell from a screencap, it looks even more like him in the actual footage. It's the right time frame for it to be Martin, too. I can't upload the film online, but if you have "A Mighty Wind" on DVD you might want to check it out.
I don't know what to make of it. It's as weird as Albert Finney in drag for a brief moment in "Miller's Crossing", something that as far as I know was never explained.
Okay, it's not that weird. But I would swear that's a young Steve Martin.
