AceShowbiz - Mark Ruffalo and Chris Evans were full of praise for a young boy who stepped in to save his sister from a dog attack.
The story of young Bridger was posted on Instagram by his aunt Nikki Walker, who started an account on the social media site just to share the incident.
"My nephew is a hero who saved his little sister from an attacking dog. He, himself, took on the attack so that the dog wouldn't get his sister," she wrote, alongside a picture of Bridger displaying his extensive injuries. "After getting bit several times on the face and head, he grabbed his sister's hand and ran with her to keep her safe."
"He later said, 'If someone was going to die, I thought it should be me.' "
Nikki tagged numerous members of "The Avengers" cast to let them know there was a real-life hero among them, and Mark was one of the first to respond.
"Dear Bridger, I just read about what happened to you and I wanted to reach out to say this... People who put the well beings of others in front of themselves are the most heroic and thoughtful people I know," he wrote. "I truly respect and admire your courage and your heart. Real courage isn't dominating people or fighting against people or walking around like a tough guy. Real courage is knowing what is right to do and doing it even when it might end up hurting you somehow. You are more of a man than many, many I have seen or known. With Admiration...Mark Ruffalo (Bruce Banner/Hulk/Professor)."
Meanwhile, Chris later recorded a special video message for Bridger, as he promised to send him an official Captain America shield.
"Pal, you're a hero. What you did was so brave, so selfless - your sister is so lucky to have you as a big brother," he said in the clip. "Keep being the man you are, we need people like you."
