After years of courtship, and a recently announced pregnancy, The Office's Jim and Pam are finally getting married. "It's going to have all the romance, all of the love and tons and tons of crazy," says Jenna Fischer, who plays Pam, of the madcap destination wedding in new behind-the-scenes footage. She and Jim (John Krasinski, who recently announced he was getting married in real life to actress Emily Blunt) will tie the knot in Niagara Falls -- a location the two hoped would deter their Dunder Mifflin colleagues from making the drive from Scranton. Turns out, that didn't work. Watch a sneak peek here -- and then tune in on Oct. 8 (8 p.m. EST) for the full episode.
