The gig marks Neeson's first TV role since a guest spot on The Simpsons in 2005 and reunites him with Linney and Platt. Neeson and Linney have appeared together in Love Actually, Kinsey and The Other Man, and onstage in a revival of The Crucible. Platt also co-starred in Kinsey and worked with Neeson on Gun Shy.
