Ok so here's the run down if you haven't watched LOTR/ read the books (LOTR= Lord Of The Rings)
Frodo Baggins: Perfectly normal Hobbit. Average in height (for a Hobbit), average in looks (thought the crystal blue eyes make me shiver), and average in temperment (he's a laid back kinda guy). That is until the one Ring falls into Frodo's hands and Gandalf (tall weird old wizard) tells him that he must destroy the ring or Middle Earth will be taken over by the evil over-lord Sauron. So Frodo end up tracing across Middle Earth all the way to Mount Doom to destroy the ring, only to have the power corupt his mind and almost ruin everything. But Frodo's ever faithful best friend Sam is there to help him. (Frodo is played by Elijah Wood. Most recently Elijah has starred in a movie called "Green Street". In the pic he is the second from the left.)
Samwise Gamgee: Frodo's cute and very loyal friend. They have always lived in each other's pockets and are the perfect example of a friendship that will last for ever. When Frodo finds out he must journey across Middle Earth Sam agree's to go with him. (Ok so Gandalf caught him gardening and TOLD Sam to go with Frodo, but Sam would've offered to go anyway.) So Sam and Frodo travell and stick together through thick and thin, even if they do disagree when it comes to trusting their guide. Sam is the one who at the end of it all turns out to be the real hero, he stopped Frodo from doing the wrong thing and didn't say "I told you so" when it turned out Sam was right NOT to trust Gollum, their guide. (Sam is played by Sean Astin who has also featured in the "goonies" and he is the third from the left in the picture.)
Peregrin Took: Pippin is one of Frodo's cousins and his ditzyness ended in him and his best mate (and cousin) Merry acompanying Frodo and Sam to destroy the ring. However things go wrong when they get captured by Orc's and end up believeing Frodo and Sam to be dead for part of the journey. Though Pippin has made his mistake's he is a true friend and loyal Hobbit at heart and when it comes to the final baattle of Middle Earth he throws himself right in and fights for what he believes in. (Pippin is played by Billy Boyed who also appears in a horror movie playing a doll called Chunkey (I think and I can't remember the name of the film) he is the one on the very left of the pic.)
Merridoc Brandybuck: Another of Frodo's cousin's. Merry is not as air-headed as Pippin and is therefore the one to get them OUT of trouble. When he ends up split up from Frodo, Sam AND Pippin, Merry becomes very lonely and the only thought that comforts him is being able to go to war and fight for his friends. Merry is a very bubbly character and often tries to cheer the others up when all hope seems lost. (Merry is played by Dominic Monaghan who also appears as Charlie Pace in "Lost" and he is pictured as the one on the far right.)
