Jesse Eisenberg, left, and Jason Segel braved the Mall of America shopping hordes to shoot movie scenes last weekend -- and did a little shopping. 

When you think of shooting locales for an arthouse film about "Infinite Jest" author David Foster Wallace, the Mall of America doesn't immediately spring to mind. But several spots around the MOA -- including Sea Life Minnesota Aquarium, Nickelodeon Universe and the movie-theater complex --   were perfect for scenes from "The End of the Tour," starring Jason Segel and Jesse Eisenberg. The film is based on a book by a Rolling Stone reporter who accompanied Wallace, who famously suffered from severe depression and killed himself in 2008, on a nationwide book tour just as he was becoming a bold-face name.Segel plays Wallace, Eisenberg the reporter David Lipsky.  Joan Cusack and Mamie Gummer were also on hand for a few scenes with the guys.

An unsuspecting audience at a Muppets movie -- not the new one, "Muppets Most Wanted," but a "free family flicks" screening of 2011's "The Muppets" --  got a special meta-experience from Segel, who starred in it. Reports critic Tim Kelly, who was there, on his movie blog Cinematallica, just as Segel " was onscreen singing his third bar of 'Life's a Happy Song,'  the projector fritzed out, the lights came on and a guy walked out.  'Hi everyone, I’m Jason Segel. Thanks for coming today. In a moment you’re going to see me sing some more songs.' He thanked everyone again, made his way back out and left a theatre of stunned parents and kids to process what just occurred."  What a mensch, that Jason!

As can be seen from this passerby-shot photo found on Tumblr, Segel was in full Wallace drag for the shoot -- long unkempt dark hair, baggy clothes, bandana tied around his dome.
