No movie special effects had ever captured that level of detail before, with ILM’s “pseudo-pod” in “The Abyss” and the shape-shifting FX of “Terminator 2" being mere appetizers for the full-on, jaw-dropping brontosaurus
There isn't a "Brontosaurus" in the movie; you're probably thinking of Brachiosaurus (and the animal known as "Brontosaurus" was correctly redesignated "Apatosaurus" over a hundred years ago).
Of the MAVERICK episodes listed, one in particular stands out and would have merited special mention: "Gunshy." I'm no expert, but I'm thinking this was possibly the first instance of a network TV series presenting a parody of another network's series. Legend has it that James Arness was not amused, though we viewers certainly were, thanks in great part to the clever script by Marion Hargrove.
