The music for the fictional band Stillwater was provided by Peter Frampton, Cameron Crowe, and Nancy Wilson of Heart. However, the credits attribute the music to Russell Hammond and Stillwater as if they were a real band.
The real title for the movie "Almost Famous" that was wanted was "Untitled." However, Dreamworks would not allow a movie to be called "Untitled," thus the name "Almost Famous" was given to the movie and the bootleg edition was given the name "Untitled."
The line "Yes, ask me again" is not in the script. This is said after Penny Lane asks William if he would like to go Morocco with her. Patrick Fugit, who played William, was stepping out of character and asking Kate Hudson to repeat her line when he said "ask me again," but Cameron Crowe kept it in the movie as he liked the take.
In most movies, another person is usually not on the other end of a phone conversation and this is edited. However, Billy Crudup, as Russell Hammond, was on the other end of the phone when Francis McDormand, as Elaine Miller, reprimanded him.
Penny Lane was not a complete work of fiction. It is stated that she is based on a real person, Cameron Crowe's friend, Pennie Trumble, who sometimes uses the name Pennie Lane.
