Bug is a recent good adrenaline kick... On DVD already and I just saw it on cable the other day.
Not really a horror, not action, just starts like some normal move and then really freaks you out.
Use it against a chick that doesn't know what it's about.
The beginning seems interesting enough to them and she'll get sucked into a regular story line. But soon that will turn to all freaked out.
She won't be able to quit the movie because she'll be into the characters, but scared shitless finishing it and you'll end up with her in your arms for sure.
