Does Actor Phil Harvey Resemble William Sylvester? The Monolith Monsters & 2001: A Space Odyssey

Part 2

Alternatively, I thought The Monolith Monsters (1957) actor Phil Harvey may resemble William Sylvester & possibly another actor, actress or group from some TV series or movie I was not quite sure of.

Connections:
- Sylvester was DR. Haywood Floyd in Stanley Kubrick's 2001: A Space Odyssey (1968). The monolith (an alien artifact) was a key to this story .
- The characters of Les Tremayne & Phil Harvey interacts early on in The Monolith Monsters. Tremayne & Sylvester were several episodes of western TV series Bonanza together.
- Phil Harvey was in A Touch Of Evil (1958) with director / actor Orson Welles. Les Tremayne (of The Monolith Monsters) had a background in radio (as did horror actor Vincent Price, Egghead in Batman).
- Welles has another link to DC Comics, having appeared in-character as Count Cagliostro from the film Black Magic (1949) in Superman no. 62 in 1950.

I also thought Phil Harvey may resemble actors Burgess Meredith & Dustin Hoffman (see part 1).
