I've been watching Billy Wilder films lately, and NetFlix provided "The Private Life of Sherlock Holmes," a weird little period piece from 1970.
In this version Robert Stephens plays a campy Holmes, mincing about and occasionally shooting up a little cocaine. Colin Blakely plays a fussbudget Watson.
The silly plot features the Loch Ness Monster and a bunch of festive dancers.
It's interesting only to the Holmes fan, and then only in the scenes at 221b Baker Street, which flesh out the idiosyncrasies of this oddest of couples.
Worth a look if you've got nothing else to do.
