On Total Recall: 
Verhoeven has moments... In particular, whenever he started to flounder and didn't know what to do, he would start throwing in violence. He'd say bring in all the rubber body parts and the blood hoses and everything and we'll start ripping people to shreds and squirt blood everywhere. And he'd keep shooting that until he overcame his nerves and got his feet on the ground and would start directing in some reasonable way again. So you'd end up with these intermittent scenes of absurdly excessive maimings at sort of intervals, and usually what he was substituting for were scenes that involved humor in the original [script]. And I realized, 'Oh, he's not good at humor. He doesn't know how to tell a joke onscreen.' Too bad, because some of the important stuff he did very well on Total Recall. It had grand moments." - Dan O'Bannon, Total Recall screenwriter
