For the first time since it was built in 1927, the famous water tower on the Warner Bros studio lot – AKA the home of the Warner Brothers and the Warner Sister Dot on the 1990s animated series Animaniacs – has received a temporary makeover. In advance of the premiere of the upcoming Supergirl series, and in celebration of the success of the CW’s Arrow and The Flash, and Fox’s Gotham, the studio has added four banners in tribute to those super hero shows. The banners will remain on display for 90 days, and were unveiled in a ceremony held tonight on the studio backlot.

That’s less important that the real estate they take up – placed below the receptacle of the water tower, they’re easily nearly as tall as the receptacle itself. As the panels were unveiled for media and WB employees, a lightshow including reflective gold ticker-tape and fireworks was presented, appropriate for the subject matter, and, let’s be honest, the hype WB hopes to generate for Supergirl, which premieres on CBS October 26.

Among the attendees of the unveiling were The Flash, Arrow, and Supergirl Executive producers Greg Berlanti and Andrew Kerisberg, Arrow Executive Producer Marc Guggenheim, Gotham Executive Producer Bruno Heller, and Supergirl star Melissa Benoist.

The Warner Bros water tower was originally located next to the studio’s fire department. It was relocated to its current location following the 1933 Long Beach earthquake. It can hold up to 100,000 gallons of water though it currently is empty.
