Gandalf touched it while Frodo had it (the length of time Gandalf spent researching is not mentioned in the films and seems like overnight but was years). The ring was like "I am going to corrupt you" scaring Gandalf and he didn't pick it up ever again.
Tom Bombadil also had it for a short time after Gandalf, still under Frodo's bearing but Jackson was like "Bombadil who?".

Overall in order of getting it, it is:
Sauron
Isildur
Deagol
Smeagol
Bilbo
Frodo
Gandalf
Bombadil
Sam
Maybe there was a river pebble wearing it while it was lost in the Anduin!
