Jeremy Renner has nothing but love for his Avengers co-stars, and said that their familial bond is real and not just a stunt for social media. Renner plays Clint Barton/Hawkeye in the MCU, who first appeared in 2011's Thor. Since his first appearance, Hawkeye has become an integral member of the Avengers, and finally helmed a standalone adventure in the Disney+ series Hawkeye.
