I was thinking of getting an Albert Brooks DVD or two and checked Amazon for prices. Instead, I was struck by the stars Amazon promotes next to the titles. What I found follows, with the unnoted actors that might have been featured instead, within brackets.
Defending Your Life: Starring Wil Albert, Sage Allen, Gary Beach, and Roger Behr [Could have noted: Albert Brooks, Meryl Streep, Rip Torn, Shirley MacLain (cameo), Lee Grant]
Mother: Richard Assad, Paul Collins, Kimiko Gelman, Isabel Glasser [Albert Brooks, Debbie Reynolds, Lisa Kudrow, Rob Morrow]
Real Life:: James L. Brooks*, Barbara DeZonia, Dudley DeZonia, and Clifford Einstein [Albert Brooks, Charles Grodin]
The Muse: Jamie Alexis, Ange Billman, Jeff Bridges (hey--how did he get in there??), and Aude Charles [Albert Brooks, Sharon Stone, Andie MacDowell, Cybill Shepherd, Steven Wright, Jennifer Tilly, Rob Reiner, James Cameron (cameos)]
Still, I can see where Amazon would want to reach out to all those Kimiko Gelman fans.
*Yes, the director, who acts in a few of Brooks's films.
UPDATE: Looks like this goes further than Brooks. According to Amazon, the stars of Citizen Kane are George Backus and the lovely and talented Fortunio Bonanova--no sign of Orson Welles, Joseph Cotten, or Agnes Morehead.
