Did you know that the Metro Goldwyn Mayer lion was not named Leo. The first lion's name was Slats (1924-1928) and was born in Dublin Zoo, Ireland on March 20, 1919, and originally named Cairbre (Gaelic for 'charioteer').
Slats was used on all black-and-white MGM films between 1924 and 1928. The first MGM film that used the logo was He Who Gets Slapped (1924). Unlike his successors, Slats did nothing but look around in the logo, making him the only MGM lion not to roar but that didn't matter because Slats made his first appearance pre-sound.
Have a great weekend!
