Maybe it's different for movies. I thought show don't tell was at a higher level than "he was nervous". It's more you can tell "James Bond is a super spy, he's super fit, and he's super suave" or you can show him early on doing things that demostrate he's fit, he's suave, and he's a spy and so no need to tell.

I'm no longer a Star Wars fan and these are not good movies IMO but this video essay on The Force Awakens vs Rouge One is a good example of show vs tell
