What shows are you connecting them with?

What shows are you connecting them with?Ray Romano starred in TNT drama Men of a Certain Age as well as his most famous sitcom Everybody Loves Raymond. Nathan Fillion I am not aware of any sitcoms he starred in, three dramas Castle, Firefly, and The Rookie. Kyle Chandler's dramas include Early Edition and Friday Night Lights as well as something recent on streaming. Only sitcom I know of for him is What About Joan, which was a big flop and not successful.
