Check out the photo. Bob claimed to be 6' 1", some sources have him at 6' 0.5". George Sanders is listed at 6' 3". Hmm.
What d'ya think? Is Bob as advertised, or could the studios have possibly exaggerated his height just a tad? Egads, tell me it isn't so!
In the movie
The Big House (1930), the scene wherein Bob is checking into prison and his vital statistics are being gathered, his height is read off as being 5' 11". Could it be so? Hmm.
Bob and George Sanders in Rage in Heaven (1941)
The studios tended to add an inch or two to all their male stars, particularly if it got their height over 6'. That was a very tall man in the 1930s. Gable's height was listed the same as Bob's. They are very close to the same height, depending upon the angle, in
Forsaking All Others (1934). And since I've thought for ages that Gable was more like 5' 10" to 5' 11", I guess I'll have to go with Bob's height as being under 6' as well. I think Bob may have been a tad taller than Gable, winning by a neck!! (Sorry, I just couldn't resist it.)
It's really not that all this matters a whole heck of a lot. It doesn't lessen Bob's stature a bit, and that's what really counts.
