With The Hobbit still on rocky ground that may or may not belong to New Zealand, Dominic Monaghan who played the Hobbit Meriadoc ‘Merry’ Brandybuck in Lord of the Rings talked about the potential that he and other Hobbit cast might appear in a cameo appearance in the prequel.
WorstPreviews quotes Monaghan:
“We’ve been saying that we’d love to come back as some sort of cameo, or turn up in the background,” he told SFX magazine. “And Peter Jackson and Fran Walsh and Philippa Boyens have said that would be a great thing for us to do, but I think they’ve got slightly more important things to deal with before they talk about the four Hobbits doing a cameo.”
While he isn’t saying they WON’T do it, its not something they are worrying about right now.
If this movie ever does manage to get made, I hope if they bother to cameo these characters in the background or something that it is subtle. These players were not even mentioned in The Hobbit, and messing around too much is just asking for trouble.
