It’s always fun when a director can insert a famous actor into their movie for a quick cameo in a way that doesn’t detract from the film.  That’s a fine line to walk, but when you get it right, you usually find out about it afterward and it just makes you like a movie you already enjoyed all the more.  The most famous recent example was the discovery that Daniel Craig was slipped into Star Wars Episode VII as a stormtrooper.  It’s something that you can definitely notice if you’re listening for his vote, but I had no clue that James Bond was wandering around Starkiller Base until I found out after the fact.  Screen Rant has put together a great video going over 10 similar instances in film history where famous stars or directors made a quick appearance in famous movies.
