The best cameo?

Cate Blanchett in Hot Fuzz.

“What? Cate Blanchett was in Hot Fuzz?”, I hear you shout. “I’ve seen that movie a gazillion times and never saw her”

You remember Nick’s ex, who was working a crime scene in the very beginning?

Her.

That’s Cate Blanchett.

Completely uncredited. That’s a proper cameo.

Speaking of Hot Fuzz.

Peter Jackson also has a cameo


Oh. Ron Jeremy had a cameo in a crowd scene in Ghostbusters.

Yup. The porn star, Ron Jeremy, appeared in Ghostbusters. A movie marketed towards kids.
