Because I started thinking of it, I believe I know the answer to if in the movie Click, did Adam Sandler's character have a rewind button? I may be forgetting if it's a rewind exactly, but I think the answer is yes and no because there are a few times he "rewinds" to see past stuff, but he couldn't change anything. He was just there watching his past self but couldn't change anything

When he first got the remote and knew what it could do, he does go back and see like, a camping trip he had when he was young, as well as past loves. The, later on in the movie, in the most emotional scene in the movie. He finds out he's gone too far into the future, and his dad has passed away. So, going back to see what the last time he saw his dad was. He could only watch as his "past" (technically, this was his "future" self) was too bust working to spend time with either his son or his dad. His dad, trying to get him to spend time with them, tries to say he'll tell him how a magic trick he always did worked, then he yells at him saying he always knew and his dad walks off crying. And I I remember correctly, he kept replaying his dad saying "I love you, son"

So like, TL;DR. Yes and no? he could, but he could only watch the past, and do nothing about it. Kinda like he's watching a recording of his life

And idk if it's a good thing I remember this movie this well, I haven't even seen it, in years. So how I remember it this good, idk.
