I prefer to watch Evil Dead.
Seriously though, I can only think of Roger Dodger maybe, or James Bond. Possibly also Wedding Crashers, but thats just cool 'cause Rachel McAdams in it (she's in The Notebook too) Not sure its 'Daygame' though. I suppose Happy Go-Lucky has a slight Daygame scene but the meeting between the main character and her partner is sort of incidental at work, but still during the day anyway.
Generally though my main taste in film is social realist, horror, sci fi/fantasy and Crime. I know this is detracting but sometimes its nice to know about the person behind the gamer and their personal taste. Maybe it'd be a worthwhile thread sometime which I may start unless someone else takes the initiative.
