It’s the ultimate pop culture get together as Entertainment Weekly gathers 12 of your favorite TV and movie casts for our first-ever Reunions issue. A sampling:

Back to the Future’s Michael J. Fox and Lea Thompson pose with an exact replica of the time-traveling DeLorean, which was lovingly created by a superfan and driven from Toronto to New York specifically for EW’s photo shoot. “It’s great being with the car,” says Fox, who recalls “hitting my knee on the flux capacitor” during filming. “It’s a thrill for me because I didn’t actually get to shoot in the car,” adds Thompson with a laugh. “I’m a little bitter!” (For more with Fox and Thompson, check out the behind-the-scenes video below.)

EW traveled to London, Sydney, and Los Angeles to reunite the cast of The Lord of the Rings — Elijah Wood, Dominic Monaghan, Sean Astin, Bernard Hill, Sean Bean, Orlando Bloom, Billy Boyd, Andy Serkis, Hugo Weaving, Miranda Otto, Cate Blanchett, Ian McKellen –and director Peter Jackson, who recalls the disorienting feeling everyone had the last day of shooting: “There were a lot of tears,” he says. “It was just very weird and sad — the feeling that we were never going to come back and do it again.” Orlando Bloom reveals that Liv Tyler also convinced him to make a radical change to his look: “She goes, ‘Orly, you should have a mohawk. You’d look really cute.’… I was like, ‘I’ll have a mohawk, please!'”

Alias stars Jennifer Garner and Victor Garber discuss how their father-daughter relationship on TV developed into a finish-each-other’s-sentences friendship off-screen, and how Garner asked Garber to officiate at her 2005 wedding to Ben Affleck. “Immediately you had stage fright, ’cause we were gonna have a big wedding,” recalls Garner. “It ended up being only four people,” replies Garber, “which I was much more comfortable with.” (For more with Garner and Garber, check out our exclusive Alias video below.)

Allison Janney — who joined her West Wing co-stars Martin Sheen, Stockard Channing, Bradley Whitford, Janel Moloney, Elisabeth Moss, Dule Hill, and Kathryn Joosten for EW’s photo shoot — says some of her fondest (and most frustrating) memories from the set on NBC’s Emmy-winning White House drama involve the practical jokes perpetrated by co-star Joshua Malina. “He hid a fish in my trailer,” she remembers. “He changed my [car’s] navigation system to Spanish, and I couldn’t figure out how to [fix] it… He was just ruthless.”

For more with these casts and 8 other TV and movie reunions — including Roots, Pretty in Pink, and Married… with Children — pick up the new issue of Entertainment Weekly, on stands Friday, October 15.
