J.R.'s son with Sue Ellen, John Ross Ewing III, was played by well-known young adult actor Omri Katz on the original Dallas series. Even though John Ross is one of the central characters of the 2012 revival series, Katz's role was recast. However, Katz had quite a bit of success during his heyday, and a few major roles that nostalgic '90s kids are bound to remember.
After Dallas went off the air, Katz had another run on the television series Eerie, Indiana, where he played Marshall Teller. Even more memorable, he played Max, the tie-dye clad protagonist of 1993's Hocus Pocus. He had guest spots on a few popular television shows afterwards, including Freaks and Geeks and General Hospital.
Katz's last role came in 2018, when he reprised the character of Marshall Teller for an episode of Childhood Thoughts. This came after a 16-year gap in acting credits. Katz is listed as a retired actor, but with a Hocus Pocus revival still in the works, we'll see if he comes out of retirement once again.
