Mark Ruffalo's kids crash Golden Globe acceptance speech as he advocates for 'Mother Earth'

Mark Ruffalo took home his first Golden Globes Sunday, and his acceptance speech –which was lovingly crashed by his kids – is getting some attention.

The actor, 53, who won for best actor in a limited series for his role in "I Know This Much Is True," appeared virtually for the event.

But after his win was announced, his children Keen Ruffalo, 19, and Odette Ruffalo, 13, joined Ruffalo and wife Sunrise Coigney on screen, giving their dad encouraging pats on the shoulder as he gave his speech. The parents also share 15-year-old Bella.

In the speech, Ruffalo focused on humanity and connectivity.

"At 54 years, it is my humble belief that what will give all this sadness and loss that we all have lived through meaning, is our common humanity," Ruffalo said. "What connects us is greater than what keeps us apart and the more than we include each other, and see each other, and hear each other, the faster we will heal our broken hearts and minds."

Ruffalo then turned his attention to climate change.

"She is Mother Earth. And we must come to balance with her and honor her. So let's be courageous together, guys," he said. "Let's turn a page on the cruel past of this nation. The good news is inclusion, and justice, and care for Mother Earth is breaking out everywhere."

Without naming former President Donald Trump, Ruffalo, a vocal critic of the ex-commander-in-chief, added the "godly light of decency is breaking through the hideous dark storm we've been living through."

"We are all in this together. We are the ones we've been waiting for. So let's do this," he concluded.

Ruffalo wasn't the only star to use their time in the spotlight Sunday to shine light on a cause.

Legendary actress and activist Jane Fonda, 83, accepted the 2021 Cecil B. DeMille Award and used her time to call attention to the glaring inclusion inequalities that still plague the industry.

She called on all of Hollywood – including the Hollywood Foreign Press Association, the 87-member group that hands out the Globes and recently came under fire for having no Black members – to make sure everyone has a "seat at the table."
