Formerly a child actor, Freddie Highmore has appeared in various roles since 2000 (via IMDb).
He portrayed a resentful child in "Finding Neverland," identical twins in "The Spiderwick Chronicles,"
It was a new challenge for him to star in a show as Dr Shaun Murphy, a surgeon with autism,
As Highmore explained to The Toronto Sun, Shaun has changed from the Shaun we met at the beginning of the series to the Shaun we see now.
Highmore joked, "I wouldn't raise my hand if a doctor were needed." Unlike Murphy, Highmore cannot discern whether the bodies on the set are real or fake.
Despite the show's 100th episode premiering, Highmore said he is "probably the worst at distinguishing between real bodies and fake bodies" of the main cast.
Additionally, the extras are known to disturb the cast members during intense scenes by loudly snoring, which ends up disrupting the film's momentum.
In that case, Highmore may easily distinguish between fake bodies and real actors.
