Journey's End (2018)

I already thought Sam Claflin was a brilliant actor before this movie, but Journey's End really drove that home in a new way. Damn is he good in this. The other actors – Paul Bettany, Asa Butterfield, and Tom Sturridge – are very good too.  

Journey's End is based quite closely on a play by R.C. Sherriff from 1928, but it does wonders with that old chestnut of a script. It's an excellent movie. I really liked it.
