I was trying to think of 'In the Shadow of Kilimanjaro'..
More giant apes:
Mighting Peking man
A*P*E* (I always wanted to see this)
Queen Kong
King Kong vs. Godzilla
King Kong Escapes
Son of kong
konga
King of the Lost World (The Asylum's KK rip off film)
Guys in Apesuits:
White Pongo (theres another White Ape film I can't think of - might actually be called The White Ape)
The Bride and the Beast
The Gorilla
Time of the Apes (shite japanes Planet of the Apes rip off)
Bride of the Gorilla
The Beast That Killed Women
The Ape
As far as I can remember the dark house Porno had a killa gorilla in it (and a gorilla handjob)
MISC:
who can forget:
Shakma
I'm sure i missed some - partically gorilla suit killas..I did ignore films like Return of the Ape Man and Monster on the campus as though the killers are apelike they are more like Neanderthals.
