THR:
The Reese Witherspoon, Chris Pine and Tom Hardy comedy received the restrictive rating for "some sexual content."

The Classification and Rating Appeals Board on Thursday upheld the R rating bestowed McG's comedy This Means War, which 20th Century Fox opens on Valentine's Day.

This Means War -- starring Reese Witherspoon, Chris Pine and Tom Hardy -- was assigned the restrictive rating for "some sexual content." Fox was appealing in the hopes of lowering the rating to PG-13. (20th Century Fox, Cinema, This Means War)
