A few theories on Smokey IS The Bandit
Here are a few theories:
1) The film shot in its entirety then screened for test audiances and was poorly recieved, scraped and re-shot.
This is the commmon theory most of us have heard. However, even though the same gag is used in the released part 3 - it was completely reshot. I'm guessing that the original plot was, as the trailer says, Gleason "becoming" The Bandit in a final attempt to catch him. The Eno Brothers could even be the motivation behind it (betting his badge). Renoylds was not involved in the shooting so I would guess that Justice would have been searching for a Bandit that he couldn't find rather than playing two roles. It's more likely that audiances would have been disapionted in not seeing Renoylds as apposed to confused.
To lend a bit of weight to the Enos being invovled watch this seen and listen for the audio overdub on the line "not that ego manic..." (from 2.53-3.20)

This scene could have been in the original, however without the whole line, we don't know who Big Enos is refering to.
2) The teaser trailer was shot then filming began on 'Smokey IS The Bandit Part 3'. The Producers didn't like the dailies and pulled the plug. Maybe shooting never even began on that script and the plug was pulled at the eleventh hour (newspaper clippings say shooting began in a weeks time. The photo of Gleason we have seen is just a promotional photo of what could have been.
3) The Eno brothers "fish" bet is there and Gleason "becomes" The Bandit to both win and catch the bandit, with Jerry Reed also as the Bandit to stop him (yeah I know....WTF!?!?!).
