I'm trying to find an old movie. Not sure of the title. I think it starred Steve McQueen; was early 1970's; about a man who get rabies somehow and has to get back to civilization/hospital before going 'mad'! Think it was called 'Rage' or 'Rabid'?? Any thoughts? :)

Maybe A Cry in the Wilderness (TV 1974) - IMDb?

There was also David Cronenberg's 1977 movie "Rabid" (which had the alternative title of "Rage").
