The Black Whip (1956)— a Regalscope picture from Charles Marquis Warren, photographed by Joseph Biroc — listed among DVD upcoming releases.

“Women of Pitcairn Island,”  is  photographed in Regalscope.

Veteran performers Lynn Bari and James Craig add a touch of professionalism to the proceedings but the star of the film is John Smith who plays Fletcher Christian’s 17-year-old son.

Smith played second-lead to Jeff Richards two years later in “Island of Lost Women.” Once again he’s on a tropical island with beautiful women.

Regalscope.

By the mid-50s, CinemaScope  had become THE cinema screen to watch and helped pull in the crowds who had turned to Television –  20^th Century-Fox then decided  that all their CinemaScope pictures would be made in colour and stereo.

B producer Robert Lippert approached Fox with the idea of having his Regal Films, Inc. produce a series of second features for the studio — two black and white CinemaScope pictures a month. For such productions a name change was agreed as  RegalScope.

RegalScope is black and white CinemaScope. Lippert made around 50 RegalScope features between 1956 and 1959 — all of them cheap, most of them Westerns. These Westerns star folks like John Agar, Jim Davis, Beverly Garland and Forrest Tucker. One, Ambush At Cimarron Pass (1958) had Clint Eastwood in  an early role.
