Well worth your time
This was a great movie! I knew nothing about Dalton Trumbo and only recently heard of him because my teenage son read his book, Johnny Got His Gun (which, by the way, is a haunting tale of the horror of a young man returning home after the war, tragically handicapped-also recommended). Bryan Cranston is absolutely amazing as Trumbo. Helen Mirren is equally convincing as Hetta Harper. Supporting cast of Diane Lane and Elle Fanning are also top notch. Be aware of frequent use of the F word, about 20 times, I'd guess. Otherwise, there is one short scene of the backside of a nude man, but not in a sexual situation. Other content that some may be offended by are drinking alcohol, continuous smoking, and popping of pills (brief, no obvious addiction). Based on the content of other R rated movies, this is very tame. I would say suitable for 14+.
