Why Arnie?

Rating: Null/10 (14 December 1998)

Why do people insist on employing the muscle-headed Arnie for films that require even the smallest degree of acting talent? I have no problem with him being in Terminator and Predator, because he's not required to act. However, the role of Doug Quaid/Howser should have gone to someone else.
This is a fantastic retelling of the original Philip K. Dick short story, and the plot twists so many times that you're never really entirely sure who the Arnie character is. Plenty of violence, a variety of high tech hardware and thoroughly stupid special effects whenever anyone is exposed to the Martian atmosphere make this a great sci-fi action fest.
My only question is how did Paul Verhoeven go from RoboCop and this to Showgirls?
