The 38-year-old actor was filming season two of The Witcher in December last year when he suffered the medical mishap but he's joked it was a 'Red Riding Hood' way of getting hurt because he was doing nothing more strenuous than running through the woods.
He said: "Obviously we had that injury, which ironically came just from me running through the woods. "It was a moment where my foot hit some dead wood and it slipped and over-contracted and just snapped."I wish it could be something cool like, 'I was fighting something monstrous', but instead I was running through the woods. It was a 'Red Riding Hood' injury."Henry has to maintain a high level of fitness all year round for the sake of his character, even though he only films for months at a time.
