Common Sense Note
Parents need to know that 45 Years is an intense indie drama that deals with mature themes like death, infidelity, and memory, some of which might be too mature for younger viewers. (Not that they're terribly likely to be clamoring to see a movie about an aging, long-married couple anyway.) One scene shows an elderly couple having sex; there's no graphic nudity, but it's clear what they're doing. There's frank talk about one character's death, as well as strong language ("s--t," "f--k," etc.), social drinking, and smoking.
A long-married couple sometimes shares affectionate moments, including hugs, warm caresses, and a sex scene that's notable for being more realistic than erotic. No graphic nudity.
Some profanity, including "s--t" and "f--k."
Love endures, but honesty is critical. Serious themes include death and infidelity.
Drugs / Tobacco /
Characters often drink wine, etc. at meals and parties or while relaxing at home. Some smoke cigarettes, including one man who resumes smoking after a long hiatus.
