ABC Entertainment president Paul Lee spoke with critics and reporters at the TCA event for ABC on Tuesday and discussed the addition of Frozen to the network's popular fantasy series Once Upon a Time.

Lee said that the integration of Frozen into the world of Once Upon a Time is a "wonderful asset," he said, as reported by TVLine. He revealed that Disney chief creative officer (and Toy Story director) John Lasseter has visited the set of OUAT in Vancouver, saying that Lasseter is "integrally related" to the planned crossover.

The network's president of entertainment also spoke to the relatively mild critical success of Once Upon a Time. He explained that the series is "a greatly underrated show" that may not get as much credit as other shows due to it being, by and large, "a big family show."

The series was only nominated for one Emmy for the latest television season, scoring its third consecutive nomination for Outstanding Costumes for a Series, this time for the Seson 3 episode A Curious Thing. For Season 2, the series was nominated for two awards, Outstanding Costumes and Outstanding Makeup for a Single-Camera Series (Non-Prosthetic). In its debut year, it was nominated for Outstanding Costumes, Outstanding Prosthetic Makeup for a Series, Miniseries, Movie or Special and Outstanding Special Visual Effects.

It has not won any of these categories.

Once Upon a Time will air the Season 4 premiere on Sunday, Sept. 28 at 8 p.m. on ABC.
