Just what was inside the glowing briefcase in Pulp Fiction? It's one of the greatest mysteries in cinema. Quentin Tarantino has remained deliberately coy on the subject, vowing to never reveal the answer. "It's whatever the viewer wants it to be," he once teased.
Except that's not true. At all. The answer is explicitly spelled out in an original screenplay draft. (Spoiler: It has nothing to do with Marsellus Wallace's soul.)
