I'm shallow and I tend not to care so much anymore when Robert Downey Jr.'s onscreen, stripped-down, resolute, and pounding on iron in a cave

*nods vigorously* I usually don't find RDJ hot, but that in that scene, he was almost as sexy as the red & gold armor. You practically want to lick the grease off him (you know, if engine grease didn't probably taste absolutely horrible).
