Clifford Bruce

The AFI Catalog lists Devil-May-Care, made in 1929, as the final credit of the Canadian stage and film actor Clifford Bruce, who died in 1919. On balance, it seems unlikely that it is the same man.

The Clifford Bruce who played Gaston the butler in the MGM film seems to have no other credited or uncredited roles, at least under that name. So far, he remains a mystery.
