Space Voyages: Return to the Red Borkin is an upcoming film adaptation of the third book in the Space Voyages canon. Filming will begin after the completion of Thaddeus and the Time Warp Trio, the series currently in production, which is estimated to wrap no earlier than 2019.
Ben and Annabella Boatwright will reprise their roles as the SILPS trio. In preliminary casting negotiations, Joseph Valdivia was tapped for the role of Thaddeus's brother, Stanley. The onscreen feline casting for Stanley has not been announced, although Sput is a leading contender for the part.
The third series will involve the SILPS trio's attempts to reunite with Thaddeus on Zarcholon, the all-BEFO planet, and come face-to-face with the emperor Lollygaggeranza, all while trying to return the Phantasm to its creator, the Red Borkin.
