Speaking to Popsugar, Sam has also opened up about how much enjoys working with Caitríona on set.
"Actually, having scenes away from her, and time apart from her, is kind of like losing someone in your family. A loved one," he said. "It's very strange, and I don't enjoy it. Whenever we're together it feels right, and I look forward to the days when we get to work together again."
