Yeah, the dream of playing as Bruce Willis didn't quite work out -- those twelve pixels don't really draw you into the idea of possessing Bruce Willis's body. But at least you get to see him during the cutscenes, right?
No, not really. Apparently each of Bruce's facial features had their own contract disputes.
So you're not quite Bruce Willis. So what? You're used to that. But here's where things really went off the rails. Delays, complications, and even a cancellation plagued the project. Activision originally intended for Bruce to play a sidekick -- he was meant to run along next to you, the game's real star, and deliver quips as he helped you kill bad guys. But, predictably, at some point during the chaotic development he was bumped up to lead.
They threw in some poorly animated strippers and just hoped you wouldn't notice the poorly done everything else.
Unfortunately, they only had audio recordings of Bruce Willis saying silly murder quips. There was no way to build a story out of a pile of absurd one-liners, right? Well, yes. You're exactly right, and that's why the results are completely absurd. Bruce Willis hardly ever talks unless it's to awkwardly open a barely-relevant one-liner. He sadistically laughs at his own slayings and talks to himself like a lunatic. "OPEN UP A CAN OF WHOOP-ASS! THAT LAST STEP'S A DOOZY!!!"
It comes across as a mean-spirited parody of an action hero starring the man who helped define that archetype. It's singularly bizarre, and we'll never see anything like it until they get Bruce Willis to star in his own Die Hard porn parody.
