Apparently they did two takes of that scene, one with Shaw sober, and one with Shaw drunk
My understanding of that scene is that Shaw wasn't able to perform the day the scene was scheduled. Loaded.
The next day he came in with a nasty hangover, but knocked the scene out of the park.

The next day he came in with a nasty hangover, but knocked the scene out of the park.

The masters of their craft seem to have that ability. Some call it the Right Stuff.

I did some checking and it seems Spielberg backs up that version. So, they did do two takes, but only used the sober (hungover) version.

Here’s an interesting tidbit that I found from the interview:

“But then when I showed the script to my friend John Milius, John said, ‘Can I take a crack at this speech?’ and John wrote a 10-page monologue that was absolutely brilliant, but out-sized for the Jaws I was making! But it was brilliant and then Robert Shaw took the speech and Robert did the cut down … Robert took a crack at the speech and he brought it down to five pages.”

So one of the few right-wingers in Hollywood, John Milius (Red Dawn) wrote the original version of the Indianapolis speech!
