The movie was originally made to play in 3-D which is why the second image has that sort of off centre red behind the black out line. Watching an old 3-D movies without the glasses actually hurts the muscles of my eyes and makes me want to almost throw up. Please don't throw up when you look at my drawing of the Creature from the Black Lagoon!!
There are two sequels to the Creature from the Black Lagoon. Revenge of the Creature stars John Agar who was married to Shirley Temple for a while. There is also a lab scene with a young Clint Eastwood as a lab technician (Eastwood also appears in another movie by Creature director Jack Arnold...The Tarantula. Clint is the pilot at the very end of the film who blows up the mutant arachnid).
The Creature Walks Among Us isn't my favourite of the Creature movies but it does have some stuff I like. Scientists decide to operate on the Creature to make him more human which is one of my favourite sci-fi plots (I think it's sometimes called Pinnocchio syndrome...a conceit of man's that everyone and everything wants to be just like him). There's a real heartbreaking ending to the Creature Walks Among Us because of the arrogant scientific manipulation. And there's a well done plot about an abusive relationship between a married couple.
Check those movies out if you haven't already seen them.
p.s. Ben Chapman, who was in the Creature costume for land sequences in the first film, was at a Comic book and Sci-Fi/Horror convention here in town recently. I watched him signing some stuff but didn't meet him. I didn't really know what to say to him.
