I know it wasn't a very serious question but I would offer that Towering Inferno and Poseidon Adventure are both centered around splashy social events where a singer and a song could be inserted organically. Where would you put a song in Swarm? That county fair?
Yes, abruptly inserting a song into the movie would have ruined it's verisimilitude completely! Thankfully, we were left with a masterpiece of realism.
Yeah, I know. But Irwin didn't set out to make a terrible movie. (I have to believe that.) Given his previous success with love songs in his disasters, I'd be shocked if the idea wasn't at least floated.
Speaking of which, I'd love a detailed account of how this picture was conceived and executed. Did Warner Bros. just rubber stamp Irwin's judgment after Inferno?
