It appears one legal battle involving Jerry Siegel and Joe Shuster's Superman is over, but it's not the one you're thinking of, and it isn't completely out of the courts yet.
The Hollywood Reporter's THR, Esq. blog today had the news that Tollin/Robbins Productions – original producers of the popular "Smallville" TV series from its days on The WB through its run on The CW – has settled out of court with Warner Bros. in a licensing lawsuit that goes back over two years.
Began in March 2010, the suit alleged that the Warner Bros. television studio that produced the show gave "sweetheart deals" to other members of the WB media empire when it licensed "Smallville" to the networks also co-owned by Warners rather than shopping it around on the open market. While no official damages were ever cited publicly, Tollin/Robbins claimed they lost out on tens of millions of dollars as WB divisions cut up the profits from the show without contractually required approval.
The producers settling out of court with Warners is obviously a boon for the studio who's been trying to keep the case from going to trial, but Tollin/Robbins wasn't the only production company named in the original case. Developers/show runners Miles Millar and Alfred Gough also were part of the original suit, represented by their respective shingles Killara Productions and Leonardtown Productions. According to THR, those suits will continue.
A June trial is expected if Warners can not settle with Millar and Gough before summer. For more, check out THR, Esq. and stay tuned to CBR for more info as it becomes available.
