Buster is getting ready for the fox hunt and has his unique assortment of dogs ready by his side.

Lou has his dogs ready for the hunt too (there wasn't a clear shot of Lou with the dogs in the film).

Buster is out looking for that fox and little does he suspect that the fox is right behind him (I highlighted the fox since he was difficult to make out in the screen shot).

Lou (or his body double) seems to have the same trouble that Buster had two decades earlier.

Not being able to go under the bridge while on horseback, Buster jumps on the bridge and gets back on the horse once the horse emerges from under the bridge.

Lou finds himself in a similar situation.

Buster tries to do the same stunt with another bridge only to find himself on a bull.

Lou finds similar results when he tries that stunt again too.
The lasso gag in the films is somewhat similar too. Keaton tries to lasso his horse, but he lassos a bear instead. Lou tries to lasso the fox but lassos a donkey instead.
According to the imdb, In Society was released by Universal in August of 1944. One month later, Universal released San Diego, I Love You. This may be pertinent because Buster has a supporting role in the latter movie. If the two movies were in production at the same time, the plausibility of Buster's participation in the A&C movie increases since he would have been physically present on the Universal lot at the time of the filming. I took a brief look through a few of my Keaton books that list some of the movies he was a gag consultant on and couldn't find any reference to this. Do any of you have any opinions on this?
