Mr. Holmes (2014)

Ian Mc Kellan is a great actor and while he plays roles that are separated by 30 years in this movie, they are of a 60 and a 90 year old man, which we as society see pretty much as about the same age, so not too difficult to pull off.  He is fighting not an ancient foe, but the one we all fight--mortality and the ability to think clearly until the end.  The elder Holmes has retired to his country estate, where he tends to bees and is working on writing his own account of a case that has haunted him for years.  He has a close relationship with his housekeeper's son and between them they manage to figure out the real end to the case, and also what it means for Holmes himself.  It is a wonderful period piece that is interesting, well acted and very much worth watching.
