FEAR AND RESPECT
out of all that, i see only Silent Hill (judging form the awesome trailer and hype its getting), Resident Evil Afterlife and 4 (Both previous movies were a success at the box office, and almost the cause of triggering that big list!)
The Getaway (Eh, actually the game was based on The Getaway, a hit movie from the 80's), Mortal Kombat is in doubts (Since its being directed by Paul Anderson, also making the RE movies so who knows) and Spyhunter (only because The Rock's in it)
The rest i can bet will make games look bad in Hollywood.
