"I'm almost ready" from my girlfriend means she's currently thinking about taking a shower, but will need at least another 15 minutes to find her hair oil, 35 minutes to wash her hair, 10 minutes to oil her damp hair, 10 minutes of drying as she looks for clips, 25 minutes of skin care, 10 minutes of makeup, 15 minutes getting dressed and 10 more minutes of looking for her shoes. With only 130 minutes, I can't finish a whole movie, so I'll go with Two Towers, as I can stop at the 1 hour 50-ish minute mark, go wait in the car for her to remember that's where she left her shoes, go out, get home and watch the last half without breaking the flow of the story.
