There is no doubt in my mind that this is the Capt- the ONLY reason I say that is- I took this pic from a succession of clips. He does look a bit ...."bloated" or "puffy" maybe it the salt air?!
These are some of the other clips that were with it....
That is very interesting on the filming of Niagara Falls, wonder if they will go over it in some scene (of course it will not be Niagara in the movie) but wondered if our Captain is about to take the big plunge...
