Thirteen at Dinner

 

 

The names on the list are the surnames of actors / actresses from movies and TV shows with numbers in their titles, like the title of the puzzle. In fact, the numbers within the titles refer to a specific person or group of people from that movie or TV show.

Seating them alphabetically by surname clockwise around the tables so that each group starts at a big chair gives the following seating:

Four Brothers Benjamin Gibson Hedlund Wahlberg The Nine Benedicto Billingsley Collins Daly Davis Guaty McBride Raver Wolf

My Two Dads Evigan Reiser Ocean's Eleven Benedict Bishop Conte Davis, Jr Fell Harvey Lawford Lester Martin Silva Sinatra

Henry VIII and his Six Wives Asher Bos Cuka Frederick Leigh-Hunt Rampling The Magnificent Seven Bronson Brynner Buchholz Coburn Dexter McQueen Vaughn

Mickey One Beatty 12 Angry Men Cronyn Danza Davis Gandolfini Harewood Lemmon Mueller-Stahl Olmos Petersen Scott Vance Williamson

The Three Musketeers Chamberlain Finlay Reed Ten Little Indians Berlinger Efroni Lister Lom McCarthy Pleasance Smith Stallone Thorp Vaccaro

Party of Five Campbell Cavarno Chabert Fox Wolf Eight is Enough Aames Goodeve Kay Needham O'Grady Rich Richardson Walters

Starting at the big chair on top and proceeding clockwise around each table, the numbers can be used as indexes into the surnames and spell the sets: IDENT / ILLIAM / OURIST / ACTORW / FROMACC / ALT. Arranging these in numerical order by the group at the head of the table spells ACTOR WILLIAM FROM ACCIDENTAL TOURIST, which leads to the answer HURT.
