In my quest to be the world's most formidable movie geek, I began formulation a theory that perhaps the afforementioned 5 actors would form the new "Rat Pack." I passed this theory to a friend of mine, and he replied "Rat Pack or Brat Pack?" "Either or, I guess," I replied. Despite that setback I decided to flesh it out. I have compiled a list of all the movies that these actors have been in, and listed them in the table below. In order to appear in the table, a movie must have three or more of the 5 actors. The only exception being if a movie includes only two of Owen Wilson, Luke Wilson and Ben Stilller, since those three began this movement in their individual pairs (Owen & Luke, and Owen & Ben.)
| Owen Wilson | Luke Wilson | Ben Stiller | Will Ferrell | Vince Vaughn | |
| Bottle Rocket* (1996) | 1 | 1 | |||
| The Cable Guy* (1996) | 1 | 1 | |||
| Rushmore* (1998) | 1 | 1 | |||
| Permanent Midnight* (1998) | 1 | 1 | |||
| Meet the Parents* (2000) | 1 | 1 | |||
| The Royal Tennebaums (2001) | 1 | 1 | 1 | ||
| Zoolander (2001) | 1 | 1 | 1 | ||
| Old School (2003) | 1 | 1 | 1 | ||
| Starsky & Hutch (2004) | 1 | 1 | 1 | 1 | |
| Anchorman (2004) | 1 | 1 | 1 | 1 | |
| The Wendell Baker Story (2004)** | 1 | 1 | 1 | ||
| The Wedding Crashers (2005)** | 1 | 1 |
* In order for a movie to be included in this entry, it must have 3 or more of the ‘rat pack’ actors in it. The only exception is for Owen Wilson, Luke Wilson and Ben Stiller. Only two of those three need appear together, as they began it.
** Not yet released, cast list could change.
