He has dyslexia
Like many stars, Orlando has struggled with the learning difficulty.
The 'Elizabethtown' star revealed in 2019 that he turned down a hosting job on 'Saturday Night Live' because of his insecurities about his dyslexia and feeling the pressures of fame - but it wouldn't stop him now.
He told DJ Howard Stern: "I was just like, partly my dyslexia, partly like that window of time where I couldn't even ... think straight and see the wood through the trees.
"You've got to read and then also ... I didn't have perspective.
"It's like you're in a burning car. When you're in our business, you get into this burning car ... and it's like ... you're in the car and you're like, 'Wow, look at this, they love it.' Then you go, 'F*** it's hot. How the f*** ... I've got to get out of this burning car.'
"The reality is you have to be able to get into the burning car, know that you're getting into a burning car, put the suit on, have all this gel so you don't get hot and burned. 'Yeah, I'm driving this burning car!'
"Then you have to get out of the burning car, make sure you've got a support team to make sure that you're safe and happy. Then you go, 'Ok, cool, I'll get back into the burning car when I do.' "
