Despite the drama involved, I only came away with one thought...
This is Charles Darwin when the film takes place:
This is the actor they hired to play Darwin, Henry Ian Cusick :
Notice a difference?
Being a bald, ugly (though admittedly not as smart) man like Charles Darwin, I take exception to this representation. You can't tell me they couldn't have hired a bald actor or (heaven forbid) shaved Cusick's head for some semblance of historical accuracy.
I know that bald isn't sexy, but WE'RE TALKING ABOUT CHARLES FREAKIN' DARWIN HERE! Sexy shouldn't factor into it!
