I know "The Girlfriend Experience" has an astrological twist to it...call girl uses astrology to posture as her client's ideal. Um...not my kind of movie, but I'm just putting it out there.
Also, pardon me for taking liberties and expanding on this theme, but sometimes you can see the astro chemistry between the actors pretty clearly.
Pride and Prejudice with Colin Firth (Virgo)and Jennifer Ehle (Capricorn)...WOW. I'll bet earth signs especially loved that one...I did, anyway
