An ent's cameo appearance!

[Saruman]

At the beginning of the level 'Fangorn Forest', you can see an ent in the background! He doesn't do anything, but it's still a nice secret! It's probably not Treebeard; I've seen a picture of what he will look like in the movie, and it's different.

Yeah, I noticed that - it's a nice little surprise. I thought I saw some sort of reflection in the water and I looked up and saw an Ent! Very cool.

In the same level, after you fight the cave troll and exit the cave, if you look at the top right of the screen, it looks like Gollum up there looking down on you, but I could be mistaken - it could be an Orc.

I think that there's also something in FOTR, which I haven't got yet. I hear that, if Aragorn finds Gollum, Gollum throws a fish at him. This fish can apparently be used as a sword for the rest of the game!
