Tyler Hoechlin will reprise his role on 'The Flash,' 'Supergirl' and 'Arrow,' while the role of Lois Lane has yet to be cast.

The CW's annual Arrow-verse crossover just got a bit bigger.

Tyler Hoechlin will reprise his role as Superman, with producers also now casting the iconic role of Lois Lane for the three-night, three-show crossover set for December.

“We couldn’t be more excited to introduce Lois Lane to the Arrowverse. This dogged, determined and brave reporter will make for a strong partner to Superman and amazing addition to our universe of DC characters,” Supergirl executive producers Jessica Queller and Robert Rovner said Wednesday in a statement.

Hoechlin will appear in all three episodes of the crossover, which stars Sunday, Dec. 9, with The Flash at 8 p.m. ET/PT, followed by Arrow on Dec. 10 at 8 p.m. and concluding Dec. 11 at the same time with Supergirl.

Hoechlin's Man of Steel and Lois Lane will appear in the crossover alongside Ruby Rose as lesbian superhero Batwoman.
