The handful of '30s and '40s black-and-white films available on Blu-ray will more than double with the very welcome March 29 release of "Sherlock Holmes: The Complete Collection'' from MPI. This is a spectacular-looking upgrade from MPI's very good-looking 2006 DVD box set containing all 14 of the 1939-1946 features starring Basil Rathbone and Nigel Bruce, still considered by many the most definitive of the dozens of performers who have appeared in these roles over the past century (most recently Robert Downey Jr. and Jude Law)
