I don't understand why you're wedded to the idea that the dinosaurs skateboard and surf... I'm not prepared to concede that part of the plot.
OK, it's NOT the central theme; we're not talking about making an Elvis movie with dinsosaurs here.
When the dinosaurs ski (or board) and surf, it represents freedom, and a sudden embracement of the awareness if their conscious being, and and the wonderment as to why it occurred.
One thing
I don't want to concede is, I want Jessie Clarke to play the Dinosaur Queen, just like she plays the Vampire Queen in
True Blood. - I can't post an image of her from True Blood because she's always naked in that TV show.
I'm thinking we make her silver, and naked, a la Rebecca Romin Stamos and that other chick in those X-Men movies (she was more of a blue, but that's kind of the idea).
Harold Ramis as Red, I'm fine with that.
As I'm considering this, byco's character seems to be the one the show might revolve around, most interestingly.
The Red character gets into this, because, like Red, the Red character is into the enhancement of food production through science - Red is already into hydroponics, and making his own beer, and stuff like that; it's good fit.
The byco character - now - he's drawn in for the discovery, and the intrigue, and the intellectual challenge - and all the while, he struggles with the responsibility of "playing God" - a la Shelly's Frankenstein (hey, there really are no new stories, just new variations of old ones) - and his worst imaginations come true when, indeed, the dinosaurs take on the unforseen anthropomorphic (see what I did there?) characteristics...
And the dilemma of what to do next occurs, as it is obvious that it is too late to "put the genie back in the bottle..."
Sam Elliott would be pretty good, actually.
Or Sam Waterson.
Maybe Sam Malone.
