CBS Boss Talks Supergirl Crossovers, Dome and POI Futures and More

Under the Dome Season 4

Supergirl will cross over with her super friends over on The CW — in a manner of speaking.

Appearing at the Television Critics Association press tour in Beverly Hills, CBS Entertainment chair Nina Tassler told TVLine, “We have not had conversations about [storyline] crossovers” between the freshman drama Supergirl and The CW’s own DC Comics-based series, Arrow and The Flash, “but we are doing crossover promotions. So you will see promotional crossovers” — meaning, ads for Supergirl airing on The CW and vice versa — “but not in terms of the characters.”

Elaborating on the issue, Tassler added, “You really have to be respectful and mindful of what each universe says you can and can’t do. Obviously, we’re working very closely with DC, and our [Supergirl] producer, Greg Berlanti, is the poster child for this field. Right now, we’re not doing it [storyline-wise]…. But we’ll always stay open.”

Other topics tackled by Tassler during her press Q&A:

* Asked about the future of Under the Dome — which just hit series lows in the ratings — Tassler previewed, “The dome is coming down at the end of this season, but that opens up a host of other storytelling opportunities” — which may or may not be enough to seed a Season 4.

* Tassler admitted the network will “probably not” re-open The Briefcase, its mildly rated, ethically iffy summertime reality series: “The show didn’t land… the audience didn’t respond.”

* Echoing that which she said at the May Upfronts, Tassler said, “We haven’t determined yet” if Person of Interest‘s truncated, delayed Season 5 will bt its last.

* Addressing the suggestion of ageism in recent Big Brother casting, Tassler avowed, “We will absolutely have characters over 40” moving forward.
