RIO DE JANEIRO — Hollywood stars Leonardo DiCaprio and Mark Ruffalo joined other celebrities making a final push for voters in Brazil to register before the Wednesday deadline, prompting dismissive responses from President Jair Bolsonaro.

In recent days, A-listers in Brazil and abroad have used their prestige and social media platforms to call for young, first-time voters in Brazil to register to vote in the October presidential election that is expected to pit far-right incumbent Bolsonaro against former President Luiz Inácio Lula da Silva of the leftist Workers' Party.

In Brazil, voting is mandatory for anyone aged between 18 and 70, and failure to vote entails paying a small fine. Those 16 and 17 can vote, but are not obligated and young people have been at the center of a nationwide get-out-the-vote campaigns.

Brazil's electoral authority says it has received a record number of registration requests.

DiCaprio, an environmental activist, has feuded previously with Bolsonaro over the Brazilian leader's efforts to expand development in the Amazon rainforest.

With the deadline nearing, DiCaprio sent three posts on his official Twitter account — all written in Portuguese — to encourage registration.

“Sixteen and 17 year olds have the power to help build Brazil’s future,″ he wrote in one, linking to a website with step-by-step instructions on how to register. "To exercise this power, you need to register to vote by 23:59 today.”

Ruffalo has also used social media, retweeting to his 8 million followers a selection of short comic videos made by Brazilian teenagers explaining how to register.

“Let’s rock this campaign! Democracy and the planet win,” Ruffalo wrote on May 1, using the trending hashtag #TiraOTituloHoje, which translates as #RegisterToVoteToday.

LOS ANGELES — Comedian Dave Chappelle was tackled during a performance at the Hollywood Bowl Tuesday night and a man was later arrested.

Security guards chased and overpowered the attacker, and Chappelle was able to continue his performance while the man was taken away in an ambulance.

The assailant was carrying a replica handgun with a knife blade inside, authorities said.

Isaiah Lee, 23, was detained and arrested for assault with a deadly weapon, said Officer Alba Mendez, a Los Angeles Police Department spokesperson.

Lee was treated by medical staff for an unspecified injury and was booked into jail early Wednesday and held in lieu of $30,000 bail, Mendez said. It was not immediately known if he had retained a lawyer.

Mendez said a “famous comedian was performing” when Lee jumped onto the stage, tackled the celebrity and produced the replica handgun containing a knife blade. Mendez said the department did not name the celebrity because it does not confirm victim names.

Chappelle was performing his stand-up routine on the last of four nights at the amphitheater as part of the “Netflix Is a Joke” festival when the man rushed on stage and tackled him. Jamie Foxx was in the wings of the stage and Chappelle thanked him for responding to the attack. Chris Rock was there as well. He grabbed the mic and jokingly asked, “Was that Will Smith?”

“The performances by Chappelle at the Hollywood Bowl were epic and record-breaking and he refuses to allow last night’s incident to overshadow the magic of this historic moment," Chapelle's publicist Carla Sims said in a statement. “As unfortunate and unsettling as the incident was, Chappelle went on with the show."

Gary Oldman might just take his Oscar and run.

The Academy Award-winning “Darkest Hour” actor — and two-time nominee — told Deadline in a recent interview, “Retirement is on the horizon.

“Yeah. I can see it,” Oldman, 64, told the outlet, adding that if his role as Jackson Lamb in the new Apple TV+ series, “Slow Horses,” is his farewell part, he’d go happily.

“To be able to sort of wrap it all up playing Jackson Lamb, I would consider myself very honored and very lucky to be able to do that. I would never say never,” said Oldman, also noting he could see himself “playing Jackson for the next how many years.”

The Brit’s remarks come on the heels of several other actors announcing their plans to put acting on the back burner.

Bruce Willis’ family in late March announced that the “Die Hard” and “Sixth Sense” star, 67, would be “stepping away” from acting due to his diagnosis with aphasia, which affects a person’s abilities to communicate.

Also in late March, Jim Carrey revealed he’s “retiring but ... It depends if the angels bring some sort of script that’s written in gold ink.” Then, he said, “I might continue down the road, but I’m taking a break.”

Andrew Garfield last week made headlines when he said that he, too, would be taking a break from acting, though he later clarified he’s “gonna have like a holiday. ... I’ve been loving the work I’ve been doing but also, I need to take a month or so.”
