It isn’t my usual sort of movie. I watched it because I couldn’t muster the concentration or effort to find the remote, due to a fever on the edges of delirium. For some reason, it stuck, and upon watching it again after I got well, I found that I liked it. (And, more relevantly, that I had actually understood it properly the first time, despite irrelevant commentary from the talking cactus on top of the TV.)
I got to use that bit before Rob did, but rather after Heinlein–I was playing a character who got resurrected in front of his nagging wife. “We said, ‘Til death do us part.’ I died, we parted!” (Delivered in a blend of Londo Mollari and Miracle Max voices, by the way.)
