This guy seems alright. He has a good look anyways. I'm excited for this movie, Marvel needs something new or we'll get burned out on all the Cap, Iron, Thor stuff.
Honestly it just sounds like he happened to be on set visiting a friend the same time as Edgar Wright and has no idea what he is being asked about. He isn't sounding coy or secretive, rather just comes across as completely baffled.
Hammer is older than Einstein was when he first published his papers on special relativity and matter-energy equivalence. Newton had already established a name for himself by that age as well.
