The CW has promoted the February 23 premiere of “Superman & Lois” as a 2-hour event.
The promotional graphic appeared at the end of the latest episode of “Batwoman,” with star Alex Garfin promoting the announcement via his Twitter account.

It’s unclear whether the 2-hour event will be a movie-length premiere or the first two episodes played back-to-back.

I hope it will be a two hour pilot. Did the Flash, Arrow,Legends or Black Lightning have a two hour series premiere? Supergirl Originally Premiered on CBS I think. And I don’t think it was a two hour premiere. I could be wrong though. It’s been a while since I’ve seen Supergirl’s pilot. I’m thinking that if the other shows had two hour pilots then Superman and Lois might be a two hour pilot as well.
