The LEGO Batman Movie is just a couple of days away, and Warner Bros. is using all of its resources to help get the word out. The latest promo videos cross LEGO Batman with The CW’s superheroes like Supergirl, Arrow, and The Flash, as well as the cast of The Big Bang Theory.

The first, above, is my favorite of the bunch. LEGO Batman confronts the other heroes and has a little trouble spelling “Kryptonian”. It makes for a pretty funny promo. Check it out!
