Actor Tom Holland has been praised for his "powerful" words after opening up about the impact dyslexia has had on him. The Spider-Man star revealed he turned down presenting Saturday Night Live (SNL) because of the "concept of trying to read something and they [the words] change". The US comedy sketch show features cue cards to guide hosts through their performances. "They've asked me a few times to do it and the truth is that I'm just really scared," he said, adding he's "heavily dyslexic".
