When the guys were preparing to make This Is Spinal Tap, they did apparently play a lot of club gigs around Los Angeles to get their chops up. They can actually play. This Is Spinal Tap has got to be one of my favourite all-time comedies.
All three main actors (
Christopher Guest,
Michael McKean,
Harry Shearer) all have quite distinguished résumés.
(IMDB lists Harry Shearer's voice contributions to The Simpsons as: Charles Montgomery 'C.M./Monty' Burns, Waylon Smithers Jr., Nedward 'Ned' Flanders, Principal Seymour 'Spanky' Skinner, Otto Mann, Reverend Timothy Lovejoy, Dr. Julius Hibbert, Kenny Brockelstein/Kent Brockman, Jasper, Lenny, Eddie, Ranier 'McBain' Wolfcastle, Scratchy, Kang, Dr. Marvin Monroe, Jebediah Obadiah Zachariah Jedediah Springfield/Hans Sprungfeld, Additional Voices.)
In addition, the movie has some absolutely hilarious cameos from several actors who were either big names or up-and-comers... Billy Crystal, Fran Drescher, Dana Carvey, Howard Hesseman, Paul Shaffer ("I want you to kick my ass"), Angelica Huston.
Gilbertrules: If you haven't seen This Is Spinal Tap, go out and rent it. You WILL NOT be disappointed.
