 Studio scenes taking place at the "Comet Studios" were taken at the  derelict Mack Sennett "Keystone" studios, where such comedy greats  as Charles Chaplin (qv) and Ben Turpin (qv) worked early in  their careers. Sennett built and moved to a larger studio earlier in  the year, so director King Vidor filmed his slapstick studio scenes  at the older, vacated site.
