When World Collide (1951, 81m, Paramount) Starring Richard Derr and Barbara Rush. George Pal produced and did the special effects (but didn't directed -- He'd start doing that a few years later). Two planets are flinging their way through outer space -- one is going to hit and destroy Earth, while the other is close enough to being Earth-like that people build a space ship to reach it to save themselves from dying on the Earth. The film ends just as that ship lands on the second planet. Of course, as this planet continue to fling through space, it'll move either closer to or further from the sun, killing everyone on it -- Everyone that is, that survived the meteors showers which occurred as this planet passes through the debris left by Earth & the other planet colliding and being destroyed -- but you're no supposed to think about that....

I'm not sure about the "to his bride" line, since as far as I can tell, Pal wasn't married to anyone noteworthy - All I could find about her was that her name was Zsoka Grandjean. It might possibly be a reference to Bride of Frankenstein (which any horror movie fan knows is the best "Frankenstein" film, and inspired Magenta's hair-do in the final scene) although Pal didn't have anything to do with that movie. I guess it was the only thing O'Brien could think of that rhymed with "Collide".
