Forget it, Don. It’s …”Mad Men.”

Veteran screenwriter Robert Towne (pictured) is among Matthew Weiner’s new recruits to “Mad Men’s” writing staff for the upcoming seventh and final season, which AMC announced Monday will unfold in two seven-episode batches in spring 2014 and spring 2015.

Towne is serving as a consulting producer for the AMC/Lionsgate TV drama series. He won an original screenplay Oscar for 1974’s “Chinatown” (a source of many oft-quoted lines including: “Forget it, Jake. It’s Chinatown”). He earned three other Oscar screenwriting noms, for 1973’s “The Last Detail,” 1975’s “Shampoo” and 1984’s “Greystoke: the Legend of Tarzan, Lord of the Apes.” Recent credits include “Mission: Impossible II,” “Without Limits” and “Days of Thunder.”

Another film vet, Patricia Resnick (“Nine to Five”), is also on board as a consulting producer. Comedy scribe David Iserson, an alum of “Saturday Night Live” and laffers including “New Girl” and “United States of Tara,” has signed on as a co-producer. And writers’ assistant Carly Wray has been upped to staff writer from writers assistant last season.

Exec producers for season seven, along with creator Matthew Weiner, are Scott Hornbacher and Janet Leahy.
