Yep. He was in a 1959 adaptation of The Hound of the Baskervilles and 1984's The Masks of Death. He also apparently replaced Douglas Wilmer in a late 1960s Holmes BBC TV series, but I can't find a page on the series (apparently it was simply called Sherlock Holmes).

I was wrong, it's not Cushing in that picture.
