Cinema Sins has put together an Everything Wrong With The Guardians Of The Galaxy video. These are always fun to watch, but this one seems a little nit-picky to me… and to James Gunn who actually addressed one of the things brought up in the clip. The technology involved in Peter Quill playing his cassettes.
From his facebook page:
I'm getting a lot of questions about the AA batteries in Quill's Walkman, and how Quill's Walkman can survive for so long.
GUYS, THEY HAVE THE ALIEN TECHNOLOGY TO TRAVEL FASTER THAN LIGHT BETWEEN PLANETS, I think they can figure out an alternative power source for the Walkman, and they likely also have technology to slow the degradation to the tape and player. This seems obvious to me.
