Rami Malek was not a household name when he put on those red contacts as a member of the Egyptian coven that helps the Cullens fight the Volturi in the final installment.
He had starred in the Night at the Museum movies with Owen Wilson, Robin Williams and Ben Stiller as the Egyptian pharaoh Ahkmenrah.
Kristen Stewart was, of course, a big star as the face of the Twilight franchise, and these days they both have even more exciting careers and apparently party in mutual circles.
