Ok. Thought I recognized that Tinker Bell one. It was taken from the DisneyLies.com, a satirical Disney site filled with mostly lies. I'm still kinda wondering if they are telling the truth when they say it's a website.
Here's what it says in their Urban Legends section:
The Legend: The mysterious briefcase in Pulp Fiction contained Tinkerbell.
Behind the legend: According to notes found in the waste paper basket of Quentin Tarantino, this is true. The contract between Disney and Miramax required the latter to release at least one film each year that featured a Disney character in a significant role, and this was the company's way of meeting that obligation for 1994.
Same thing goes for the PotC question... DisneyLies.com as well:
The Legend: Parts of Pirates of the Caribbean: Curse of the Black Pearl were filmed within the Pirates of the Caribbean attraction.
Behind the Legend: Yep. And The Haunted Mansion was filmed in the Haunted Mansion. Same deal with the Swiss Family Robinson Tree House. A big chase scene from Speed was filmed on the Autopia, too. Really.
Somebody out there is just going about stealing urban legends from a site filled with lies....
