Per yours and Lolita's postulations that Cyril soldiered on because he cared deeply about his craft, I've found one item which may support that: in 1921, Cyril's among a handful of younger actors who create an after-hours review to entertain the theatrical community. Seems to be a rather innovative project, and it's under the aegis of several heavy-hitting guilds/clubs; Lambs, Friars.
Cyril's face-time from all those films can't add up to more than 3 hours altogether, maybe less. From this distance, it does seem terribly futile as the work of a lifetime, but, in the end, impossible to know how Cyril saw it.
Cyril's last film part was in 1951, and that's the same year he came into a good inheritance. I did find that he was manager of a very good Hollywood restaurant in the late 1950s - huge bar, established regular hangout for famous movie folk - but I've no idea if he'd been doing that when still working in movies.

Saturday the fun begins! Those dizzy goofs on their way direct from three big weeks in Cleveland,
