Looks as if the 1973 tv series "The Magician," which starred Bill Bixby as conjuror/crime solver Anthony Blake will be coming to DVD, courtesy of Visual Entertainment, Inc (VEI). TV Shows on DVD has a little more information here.
Don't confuse Anthony Blake with Elliott Blake (Anthony Andrews), the murderous magician in "Columbo Goes To the Guillotine." Or either Bixby's series or Andrews' tv movie with Hal Linden's series "Blacke's Magic" , (1986), in which Linden played magician/crime solver Alexander Blacke. But you wouldn't have, anyway.
