Props from other movies that were in Superman

After watching Superman last night for the first time in a long time, I noticed a lot of props from other films. I probably missed a bunch so how about a list. And why is it after 30 years this movie still gets to me emotionally every time?

Obi-Wan's case
I swear that Lex's terminal (from the expanded cut) looks like a Death Star terminal
The headsets used on the Falcon
John Ratzenberger

Any others?
