Her production company, Donna and Shula Productions, described her passing as “a moment of great sorrow for the family, friends, and colleagues.”

The company also moved quickly to address speculation circulating in Israeli media that Greek investigators were exploring a possible Iranian connection. In a rare public clarification, it firmly dismissed the claims, stating there was no evidence of “a criminal or nationalistic-related death” and emphasizing that the rumours “are not true and are unfounded.”

Under Greek law, a postmortem examination is automatically conducted in such cases, followed by a formal investigation, according to The Guardian. Within hours of the discovery, authorities had launched an inquiry, gathering testimony from hotel staff and requesting security camera footage.

Police spokesperson Constantina Dimoglidou appeared to rule out foul play. She told media outlets that Eden’s brother shared that his sister had been taking medication for a medical condition that had previously required hospitalization.

Eden, born in 1973, was a major force in Israel’s thriving television scene and earned international acclaim, including an Emmy Award for her work on Tehran for Apple TV+. She had been in Athens since February 4, focused on producing the upcoming season of the spy thriller.

The producer was considered one of Israel’s most successful television creators and was behind several notable productions, including “Saving the Wildlife,” “Magpie,” and “Shakshouka.”

Praise for its realism

Israel’s public broadcaster, KAN, paid tribute to her legacy, saying: “We are saddened by the passing of our friend and partner in a long line of productions, series, and programmes.

“Dana was among the senior figures in the Israeli television industry and played a central role in creating and leading some of the corporation’s most prominent and influential productions.”

Tehran, led by actress Niv Sultan, follows Mossad operative Tamar Rabinyan, an Iranian-born agent raised in Israel who is sent undercover to sabotage Iran’s developing nuclear program. The series also featured Glenn Close in a major role during its second season.

The drama has earned praise for its realism. The New York Times once described it as so convincingly crafted in its depiction of Israel’s intelligence operations that “even the FBI director endorsed it.” At the same time, Iran’s government has repeatedly condemned the show, branding it Zionist propaganda.

The series’ global popularity prompted Apple TV+ to greenlight a fourth season in December.

KAN said Eden’s influence would endure long after her passing.

“Her professional and personal legacy will continue to shape Israeli television for many years to come,” it said.
