The teaser trailer for Mr Holmes, is finally here. The film is slated for a summer release, and sees Ian McKellen return to the screen in a much more mature avatar, than before. The year is 1947 and Sherlock Holmes is now 93-years old, so his acute mental stamina, has reduced somewhat. He has moved into a Sussex farmhouse, with his housekeeper and her younger son, Roger for companionship. Holmes begins to depend upon the young boy, when he goes back to an unsolved case that forced him into retirement, and deal with his subsiding health.
