The film criticism show Ebert Presents: At the Movies will go on hiatus at the end of December, according to a blog post published Wednesday by Roger Ebert. The public TV program was produced and nearly entirely financed by the Chicago Sun-Times film critic and his wife, Chaz Ebert, and was intended to be a continuation of the various review shows hosted by Ebert and the late Gene Siskel, such as Sneak Previews, At the Movies, and Siskel & Ebert. But the Eberts said they can no longer afford to foot the bill and are now searching for new sponsors.

“We’ve spoken to the top executives of several channels and film distributors, charitable foundations, web delivery services, potential corporate sponsors, and crowd-funding sources,” said Ebert in his post. “We are still talking with them, but the time crunch has intervened. It is a complicated process, and so we are going on hiatus while we sort it out.”

Ebert Presents: At the Movies is hosted by critics Christy Lemire of the Associated Press and Ignatiy Vishnevetsky of By the end of the year, the show will have aired 50 episodes.
