Confused

In silent film, George Valentin
was the era's greatest treasure,
with Fairbanks' joie de vivre and Gilbert's
charm in equal measure.

They'd said in Twenties Hollywood
his star power was unmatched.
I'd heard enough -- a poem was due!
A research plan was hatched.

Well...

I've searched for bios, stills and clips
until almost demented,
with no results!  I swear, it's like
this artist was invented!
