Gandalf's account takes place after his "death" in the mines of Moria. I will talk about a scene and then have Gandalf's comment below. This only contains the first movie. Part two to follow.

*After company is surrounded by elves in Lorien and Gimli is afraid*

Gandalf: Just like a dwarf. (sighs heavily)

*The company meeting Galadriel*

Gandalf: (Smiles) The Lady Galadriel, as lovely as ever. (Wistfully thinks back to his past) She will give them aid and guidance where I could not.

*When Frodo is shown the mirror*

Gandalf: The future has yet to be written. Keep pressing on, and write the future with loyalty, courage and above all, hope.

*Saurmon orders the orcs to attack*

Gandalf: you shall pay dearly for the blood spilt at your command.

*Frodo is given the light from Galadriel*

Gandalf: (Smiles ) one could not ask for a finer tool. Carry it well, Frodo.

*Frodo wanders off by himself in the woods*

Gandalf: (sadly shakes head) one with burdens such as yours should not walk alone. It is unwise. Go back to the company.

*Boromir attacks Frodo for the Ring.*

Gandalf : foolish man! You will regret your actions!

* Merry and Pippin distract the orcs so Frodo can get away.*

Gandalf : (frowns) such foolish hobbits! (Smiles slightly) but brave ones.

*Boromir dies trying to defend Merry and Pippin.*

Gandalf : Your actions have been paid in full. Rest now, Son of Gondor. Rest in the knowledge that you have redeemed yourself.

*Merry and Pippin are taken by orcs*

Gandalf : Be brave and stay together! Darkness shall not invade this land forever.

*Sam follows after Frodo in the water*

Gandalf : ( Smiles ) you shall do well on the journey ahead, Samwise.

*Gimli says the fellowship has failed*

Gandalf : it is not the quantity but the quality of the remaining fellowship.
