So how did Warner Bros end up coming aboard Paramount’s “Interstellar”?

Seems the WB had something Paramount wanted in return.

The water tower shingle made a deal with Paramount that’ll sees the Melrose hub nab the rights to the “Friday the 13th” series, and also share in the profits on a future “South Park” movie, and in return the WB gets “sharing” duties on Christopher Nolan’s highly-anticipated “Interstellar”, out next year.

What Paramount has in store for Jason is unknown, but Warners weren’t doing much with him – the last “Friday the 13th” film was the Michael Bay produced reboot from a few years back, with no recent word on a sequel.

By the same token, the one and only “South Park” film was 1998’s “South Park : Bigger, Longer & Uncut”.
