Alpha Video has released a 3-DVD set of Houdini's Terror Island, The Man from Beyond, and Haldane of the Secret Service. Alpha had released a bundle back in 2013, but they've whipped up new cover art for this one. Alpha's releases contain their own musical score.
Why no TheGrim Game, Alpha? It's just waiting for a distributor HERE.
You can purchase Alpha's Houdini set on Amazon.com.
