While Lisa was unsurprised by the Avengers: Endgame actor’s win, she revealed her son was shocked.
She said: “He’s always amazed at his own success, he’s amazed at what people think of him.”
And though she is proud of Chris’ new title, she thinks his friends will see it as a reason to poke fun at him.
She said: “[His friends] will absolutely give him grief about it, but – they’re very funny.”
Chris admitted when his win was announced that his mum would be “so happy” about it.
He said: “My mom will be so happy. She’s proud of everything I do, but this is something she can really brag about.”
The Knives Out star admitted earlier this week he has to take better care of himself now he is in his 40s.
He said: “In the good ol’ days I could eat whatever I wanted, do a couple workouts per week and be okay.
“That is not the case anymore. If I have two beers, I wear it. I haven’t had to play a role like Captain America in a while so things like diet and workout regimen haven’t been on my radar. But getting older, things are clicking and sore and it’s harder to wake up, you have less energy...
“You know what it is? It’s that it happened so quickly. A year ago I wasn’t thinking about any of this. I was someone who was lucky enough to not really think much of it in my 30s and then I hit 40 and it all came at once.”
