FLASHBACK: Robert Downey Jr. is Incredibly Bashful in 1987 Interview: 'Actors are so Insecure'

Before the Avengers assembled...

Before suiting up as Iron Man in the Marvel Cinematic Universe, Robert Downey Jr. was the 22-year-old fresh-faced actor making waves in Hollywood.

ET sat down with RDJ back in 1987 to talk about his blossoming career.

“It's strange, driving down the street and having people kind of accost you verbally,” RDJ told ET of his newfound fans.

Though he was in the early stages of his career, Downey received praise from fans and critics alike for his starring roles in Less Than Zero and The Pick-up Artist – a badge of honor he wore humbly, considering he had a hard time seeing his own face projected on the big screen.

“Actors are so insecure,” he joked.

We pretty much had to beg – please, say ONE nice thing about yourself!

“That'll be my one self-indulgent statement,” said Downey. “I'm a damn hoot!”
