Anyway, I watched Leviathan first, mainly because I love Peter Weller. With the exception of this and the Robocop movies, he can really pick the shitty movies. (And yes, I'm talking about Buckaroo Banzai. Damn, that's a piece of shit.) It also has Richard Crenna and Hector Elizondo, both of whom I enjoy.
Funny thing about Leviathan is that the monster never gets that big. Not to what I would call Leviathan-sized. Regardless, it's a pretty decent movie for what it is, which is basically Alien underwater. And I'm ok with that. Mainly because of the end scene and Peter Weller yelling, "Say ah, motherfucker!" Totally worth it.
I saved DeepStar Six for second because I wasn't aware of any Peter Weller-caliber actors in it. That is until I started watching it. It's got goddamn Miguel Ferrer! That checks him off on my "People I Like From Robocop" list. Only one I need for the hat trick is Kurtwood Smith.
Anyway, while we're talking about cast, let me blow your mind. It's got fuckin' Lloyd Braun in it! From Sienfeld! I sat there staring at that guy trying to place him for like 10 minutes. I finally IMDB'd him and figured it out. You want to know the best part? The diving suit in the poster there gets bitten in half by the monster. Guess who's in it?! Lloyd Braun! I was ecstatic!
I guess what I'm saying is, 1989 was a good year for underwater alien-monster movies.
