And then there's this argument about who framed roger rabbit...

I've seen the original; finger definitely is where it shouldn't be.

That is an urban legend, the ghost part anyway. You can see something that looks like a ghost in the film though. It is, in fact a cardboard-cutout of Ted Danson's character. Storyline featuring the said cutout was cut from the film, but is visible elsewhere.

In Home Alone 3, during the middle of the film, The Alex who is left home with the chicken pox reaches under his bed to get a gun that has a remote attached to it. when he grabs it you can see that it is indeed a gun with trigger and everything. but the camera closes in on the "gun" and you will see that it is just a metal tube with a tv remote attached to it.

In Harry Potter and the Prisoner of Azkaban, Harry is underneath the invisibility cloak throwing snow balls and Malfoy, later in that scene Harry is dragging a slytherin by the coat, on close inspection you can tell that Harry isn't leaving any foot prints in the snow!

This is kind of a "hidden in plain sight" sort of thing.

In "Goldfinger," as the pilots are flying over Fort Knox, there's a quick shot of the base with a sign reading "Welcome the Fort Knox" with the commanding officer's name given as "General Rushon." In fact, CAPTAIN Rushon was the liason for the Army working with the studio. The producers thought his name popping up on the screen would be a good joke and a quiet "thank you" for the work he did.

...another couple of not so hidden, hidden Bonds.

In "Thunderball" as Bond is running through the Madi Grais, notice the group of dancers with "007" on their heads. The producers made the mistake of telling the people which film they needed floats and costumes for and they thought they were being clever. The costumes were so well done, the producers decided they had to fit them in somewhere for a quick second, but it's still odd. (Although I'd seen the film a half a dozen times and didn't pay any attention to the costumes until I was told it was going to be there.)

And in "Live and Let Die," Jane Seymour plays a woman who can tell the future with a Tarot deck. Supposedly (I haven't seen the film in years and can't confirm this) her Tarot deck has a "007" design worked into the back!
