Open thread: What's the best movie cameo?

It's fairly hard to discuss cameo appearances in films without giving something away: most of the time, when a cameo works well, it's down to an element of surprise. When (SPOILER ALERT) Sean Connery turns up as Richard the Lionheart at the end of Robin Hood: Prince of Thieves, or when (SPOILER ALERT) David Bowie shows up in Zoolander, the unexpectedness of seeing such well-known faces in such fleeting roles is more-or-less the main point. However, the reverse is true when it comes to the king of cameos, Alfred Hitchcock, who appeared in 39 of his 52 major films – the enjoyment comes in part from anticipating the cameo you already know is coming. So, presupposing a big SPOILER ALERT for the whole thread, tell us below what your film movie cameos are. We're also keen to hear about new films you've been watching. Here's what some @guardianfilm followers had to say about movies they'd seen recently: @theinsaneramble The Dark Knight Rises: Beautiful, emotional, energetic, exciting, wonderful characterisation, brilliant storytelling, amazing ending. @Antmeist33 Dark Knight Rises – Breathtaking epic and great performances, making this a stunning finale to a superb trilogy. @SamMasonBell Dark Knight Rises – superb but also hugely deeply flawed yet still best film of the year so far. @DuncanVB Spiderman: the flaws and similarities to Raimi's film don't matter when the core elements are so strong. Quickest 135 mins ever. @WilliamConboy The Amazing Spiderman – In the era of digital; geek-chic & attitude prevail amidst a study of character-creation and connection. @burntcopper Magic Mike: a rather good, funny, naturalistic slice-of-life film with added eye candy. @saharailyas Magic Mike: what could've been the male showgirls is ruined by terrible meaningful instagram scenes. @helinski Seeking a Friend for the End of the World, sweet, sharply funny & warm, sort of Garden State meets Deep Impact with more vinyl. @raptureponies The Raid Redemption: Really enjoyed the most creative movie deaths i've seen in a while. • If you've seen any films in the last week, good or bad, let us know.
