The word game in John Michaels's apartment has the words:
MARIA MALONE NAME MOTHER
Maria Malone is the name of Jack ex-wife and mother of his daughters.
Goof: When Jack is standing over Helen/Hope's dead body, the actress (Susan Misner) is seen twitching her left eye twitching.
Goof: Jack continues to pull the trigger of his Glock G23 after running out of bullets. It isn't possible to 'dry fire' a Glock more than once because the slide must be re-cocked to recharge the weapon after each trigger pull.
