I think the Russell Brand made an amazing Trinculo. Russell is always seen as playing a drunk and funny man in his movies, and I think that this is no exception. I looked up the character analysis for Trinculo, and this is what I found.
“A consistently drunken jester, who is a servant of Alonso’s, and brought ashore in the shipwreck. He is a dull fool mostly, not capable of any real action, and providing a good deal of comic relief.”
It kind of reminds me of his character in “Forgetting Sarah Marshall.” Russell is hilarious and this pictures depicts him perfectly
