Udo Kier, a German actor and cult icon who collaborated with everyone from Andy Warhol to Lars von Trier to Madonna, died on Sunday morning, according to his partner, artist Delbert McBride. He was 81.

Among the more than 200 films in his expansive body of work, Kier’s breakout collaborations with Warhol are among his most celebrated. Kier starred in the titular roles in both 1973’s “Flesh for Frankenstein” and 1974’s “Blood for Dracula.” Both directed by Paul Morrissey and produced by Warhol, the films are subversive, sultry reimaginings of the classic Hollywood monsters, with Kier bringing a haunting yet comically inept spin on the title characters.

That pair of films made Kier famous, and he spent the next two decades working through Europe and collaborating with legendary writer-director Rainer Werner Fassbinder on films like “The Stationmaster’s Wife,” “The Third Generation” and “Lili Marleen.” Then, at the Berlin Film Festival, Kier met future two-time Oscar-nominated director Gus Van Sant, who Kier credits with securing him an American work permit and a SAG card.

In 1991, Van Sant widely introduced Kier to American audiences with his coming-of-age drama “My Own Private Idaho,” loosely based on Shakespeare’s “Henry IV.” Kier appeared in a supporting role alongside stars River Phoenix and Keanu Reeves.

Around the same time, Kier began his lifelong collaboration with von Trier. Starting in the late ’80s with “Epidemic,” Kier appeared in the 1991 film “Europa” before appearing in several episodes of von Trier’s long-running horror-thriller series “The Kingdom” through the ’90s and aughts. Their other film collaborations include “Breaking the Waves,” “Dancer in the Dark,” “Dogville,” “Melancholia” and “Nymphomaniac: Vol. II.”

The 1990s also saw Kier in several supporting roles in major Hollywood productions, such as “Ace Ventura: Pet Detective,” “Armageddon” and “Blade.” He also appeared in Madonna’s book “Sex” in 1992, and made appearances in her music videos for “Erotica” and “Deeper and Deeper” from her album “Erotica.”

Most recently, Kier appeared in Kleber Mendonça Filho’s awards darling “The Secret Agent.” The film earned star Wagner Moura the honor for best actor at the 2025 Cannes Film Festival.

Born Udo Kierspe in Cologne, Germany, in a hospital that was being bombed by Allied Forces, he moved to London at 18 after meeting Fassbinder in a bar.

“I liked the attention, so I became an actor,” he told Variety‘s Peter Debruge in a 2024 interview. After working between Europe and the U.S. for many decades, Kier settled in Los Angeles and Palm Springs, where he lived in a former mid-century library and cultivated interests in art, architecture and collecting. He was a fixture at the Palm Springs Film Festival, where he warmly received accolades from fans.

The Israeli Defense Forces (IDF) released a video showing what it describes as one of Hamas’s “most complex” underground infrastructures extending beneath the southern Gaza city of Rafah. 

According to the IDF, the seven-kilometer-long “root tunnel” runs roughly 25 meters underground, contains about 80 rooms and was used for command operations, weapons storage and sheltering Hamas operatives. 

The video shared on X on Nov. 20 travels through reinforced concrete passageways and large chambers, showing the sophistication and scale of Hamas’s underground network. 

The Israeli military claims the tunnel originated beneath a United Nations Relief and Works Agency (UNRWA) compound and stretched beneath civilian sites.

ISRAEL’S DOHA STRIKE SENT A DECISIVE MESSAGE THAT TERROR WILL FIND NO SAFE HAVEN

“IDF troops uncovered one of Gaza’s largest and most complex underground routes, over 7 km long, ~25 meters deep, with ~80 hideouts, where abducted IDF officer Lt. Hadar Goldin was held,” the post read.

Israeli analysts say the demolition of this tunnel marks a strategic blow to Hamas and “paves the path to its defeat.”

“The destruction of this tunnel as well as many others like it or similar… as well as other terror facilities pushes Hamas to the edge,” said Professor Kobi Michael, senior researcher at the Institute for National Security Studies (INSS) and the Misgav Institute.

“It is one of the longest and [most] complicated tunnels that have been discovered, but it is not the only one,” he told Fox News Digital.

Michael explained that Hamas’ root tunnels form the backbone of its underground warfare system. 

“This is an example of a root tunnel, a strategic one that feeds many tactic tunnels and is used for strategic purposes [such] as command and control, weapon storage, manufacturing platforms of weapon[s] and strategic logistics,” he said.

“Such a tunnel is usually manned by hundreds of militants and commanders.”

The IDF believes this particular tunnel network may have been connected to the area where Lt. Hadar Goldin, an Israeli soldier abducted during the 2014 Gaza war, was held captive. Hamas returned Goldin’s remains earlier this month – after more than a decade. 

The tunnel’s exposure sheds new light on the extent of its underground operations.

“I have no idea about the cost but if you take into consideration the amount of the building materials, labor and facilities and its length, it is a matter of millions of INS,” he claimed. “Hamas chose routes under sensitive civilian and humanitarian facilities in order to prevent the IDF from attacking the tunnel.”

As Israel continues operations in Gaza, the destruction of Hamas’s tunnel networks remains central to its strategy to dismantle the group’s military capabilities and prevent future attacks.

In 2014, Israeli Prime Minister Benjamin Netanyahu said he wanted to destroy the tunnels, which Hamas militants used to infiltrate Israeli territory, “with or without a ceasefire.”

According to a 2023 investigation by Reuters, Hamas had said it had been using the tunnels to hide hostages seized in its Oct. 7 attack on Israel.

Israel’s military said its ground forces had uncovered around 1,500 Hamas tunnels and shafts throughout the Gaza Strip, per the report.
