AMC is going all out for the series finale of “Mad Men,” setting a marathon of episodes as a lead-up and asking its sister networks to forgo regularly scheduled programming during the acclaimed drama’s conclusion.

The network on Tuesday said that every episode from all seven seasons of “Mad Men” will air consecutively, starting at 6 p.m. on Wednesday and concluding with last week’s episode at 9. And then at 10 p.m., while AMC airs the series finale, BBC America, IFC, SundanceTV and We TV will air a special message commemorating the series.

Launching during the five-day “Mad Men” on-air event is the all-new “Times of Your Life” spot – the final promo for the series. The retrospective piece, set to the popular song that was also used in a 1970s Kodak ad campaign, is presented from Don Draper’s perspective and features memorable, moving scenes from the series. The spot, which uses the Paul Anka version of the song, will debut on Wednesday and will also serve as the curtain raiser for the final episode, airing immediately prior to the series finale on Sunday.

Additionally, AMC will air vintage promos from past seasons of the series, celebrity fan tributes and interview footage from recent “Mad Men” red carpet events. In addition, spots showcasing important first moments from the series will air in between episodes, as well as a sequence of “Madvertising” vignettes – facts and famous quotes about the advertising industry.

“Turning AMC over to ‘Mad Men’ and airing every episode of every season as a lead-in to the finale on Sunday seems a fitting way to continue celebrating what this series has meant to the fans, to television and to our network,” said Charlie Collier, AMC president. “We are also enormously appreciative of our sister networks who are paying tribute to this remarkable program that has had such an impact on our entire company.”

Off-air, as part of the “Mad Men” finale celebration, AMC is partnering with Film Independent, the non-profit arts organization, to host a “Mad Men” live-read screening of the series finale on Sunday in Los Angeles. The event will include a Jason Reitman-directed live read of the “Mad Men” season-one finale, “The Wheel,” featuring a surprise celebrity cast taking on the iconic “Mad Men” roles, followed by a screening of the series finale with the cast and creator-writer-director-executive producer Matthew Weiner.
