There's a new member of the Hudson crew stepping into the world of acting - Oliver Hudson's 18-year-old son, Wilder Hudson. The teen will make his acting debut in his dad's upcoming holiday film, A Merry Little Ex-Mas, a performance that brought Oliver, 49, to tears. "I'm sitting there listening in [on] the movie, and after his first take, I, for the first time, just started crying. Because I couldn't believe that this was my son," Oliver told People on Tuesday, October 14, of his son's performance.
