15 Historical Photos You Won't Believe Are Real
7. Leo The Movie Star Lion - MGM Opening Credits Created Using Live Big Cat
Everyone recognises the opening credits to Metro-Goldwyn-Mayer's (MGM's) films as the roar of Leo the Lion.
Well, in this photo, a lion named Jackie - who served as the second (between 1928 and 1956) of the seven wild cats that have been used to date - is standing on two boxes while recording the roar for the MGM credits in 1924.
Neither the cameraman or the sound technician look nervous at all though, do they?
