John Krasinski
The A Quiet Place star was close to quitting Hollywood until his mother convinced him to stay a little while longer – allowing him to land his breakthrough role as Jim Halpert in comedy series The Office.
He told Stephen Colbert in 2018: "I was like, 'So, I'm out. This is terrible. It's so scary. This is the worst. Waiting tables, not as fun as they say.
"And she said, 'You know, it's September. Just wait it out. Just wait 'til the end of the year. Don't give up just yet.' I was telling her to come get me. ... And three weeks later I got The Office."
