Yep he was a film star in the silent film era of which I all watched. He even made his own film studio but it was short lived due to financial difficulties with it.
I watched The Grim Game twice which was found in 2015 and bought by Turner Classic Movies it’s his best film highly recommended
Haldane of the Secret Service and The Man from Beyond which are the two films he made out of his studio
And then Terror Island
But probably his most well known was actually a serial called The Master Mystery
Serials were pretty much episodic short films and it featured one of the first robots in film and the robots name is Q.
Here is one of my favorite artworks
And here it is the real thing
