HBO's upcoming DCU series Lanterns picked up fresh buzz after its San Diego Comic-Con panel, where two notable updates emerged. The biggest development is that Laura Linney's previously secret part in the show has now been confirmed, while co-creator Tom King also hinted that a "really big reveal" is still being saved.

For viewers who have been tracking Lanterns casting news, the Laura Linney update stands out because her involvement had been treated as a mystery. The panel appears to have ended that speculation, adding another major talking point to a series that is already one of the more closely watched projects in DC's television slate.

Tom King's tease suggests the creative team is still holding back a significant piece of information about the HBO drama. While no full details were included in the early reporting, the suggestion of a larger reveal indicates that Lanterns may still have major story or character surprises in reserve.

Taken together, the Comic-Con updates help keep Lanterns at the center of DCU conversation. With Laura Linney's role now clarified and a bigger reveal still on the horizon, the series continues to build momentum ahead of its eventual debut.
