* DawsonCasting: Even though Bret was older than Bart, Jack Kelly was nearly seventh months older than James Garner.
* WhatCouldHaveBeen: A then-unknown Creator/SeanConnery was originally offered the role of Beau Maverick. Who got the part? Creator/RogerMoore.
* WrittenByCastmember: In addition to making regular appearances as Big Mike [=McComb=], Leo Gordon, also wrote several episodes of the series.

* ActorAllusion: During Creator/DannyGlover's cameo, as he and Creator/MelGibson come face to face and they act like they recognize one another, the two note guitar overture from ''Film/LethalWeapon'' faintly plays.
* AllStarCast: Within the many [[TheCameo cameos]]. Country singers and old western-actors have supporting roles, especially during the All River's Draw Poker Championship, as Robert Fuller, Denver Pyle, William Smith or [[Film/{{Blacula}} William Marshall]].
* CastingGag:
** A bank robber (who states that he's "getting too old for this") is played by Danny Glover, who co-starred with Gibson in ''Film/LethalWeapon''.
** Several cheats in the big riverboat championship are thrown overboard. The first is Music/ClintBlack, who is also the singer of the song over the very montage he's tossed out in.
* IWantYouToMeetAnOldFriendOfMine
** The [[spoiler:Danny Glover]] gag in the bank robbery scene.
** This scene is actually a two-fer. [[spoiler:Glover]] we get to see, but [[spoiler:Corey Feldman]] was also part of the gang.
