You’d be hard pressed to find a Broadway star who hasn’t appeared on “Theater Talk.” James Gandolfini, Joan Rivers, Cate Blanchett, Idina Menzel, Hugh Jackman and Cyndi Lauper have all stopped by the television show over the last 25 years, sharing both insider gossip and earnest musings on their craft.

But despite its passionate fan base and access to Broadway’s high-wattage talent, “Theater Talk” has come to close. Its last show aired in July.

Susan Haskins, the show’s host and executive producer and a co-creator, said the show ended after a change in leadership at CUNY TV, which broadcast the program, led to a dispute over editorial control.

A representative from CUNY TV did not respond to requests for comment.

“To me, it’s an art project,” Ms. Haskins said of the program in a phone interview. She added: “I don’t see a vision in going corporate or having overseers.”
