There’s a throwback vibe for sure, mainly to the celebrity-packed films of yesteryear like It’s a Mad, Mad, Mad, Mad World, The Cannonball Run and the superior 1974 Orient Express adaptation (with Lauren Bacall, Sean Connery, Ingrid Bergman and more).
These films were often glitzy showcases of a multitude of mostly B-and-C-list movie stars, actors known primarily for TV, or in other realms of sports/showbiz (as in The Cannonball Run , with everyone from Burt Reynolds and Roger Moore to Sammy Davis Jr., Jamie Farr and Terry Bradshaw), or former big-time actors whose careers had already begun to congeal (think It's a Mad Mad Mad Mad World , with Spencer Tracy, Milton Berle, Sid Caeser, Ethel Merman, Mickey Rooney, and Jonathon Winters).
