According to the Heatvision blog, that's exactly what Bruce Willis, John Malkovich, and director Robert Schwentke (The Time Traveler's Wife, Flightplan, Tattoo) are doing this weekend for their upcoming action comedy, Red, the big-screen adaptation of Warren Ellis and Cully Hamner's comic-book miniseries for Wildstorm Comics (a DC Comics imprint). They're back in Louisiana, where parts of Red were shot earlier this year for Summit Entertainment. Willis, Malkovich, and Schwentke are shooting a new post-credits tag or "button" (in the parlance of some critics and industry types) as a treat for moviegoers who decide to sit through the end credits. Willis' other co-stars, Morgan Freeman, Helen Mirren, and Mary-Louise Parker, weren't mentioned in Heatvision's report, so presumably they won't appear in the new scene.
I was among the fortunate few to catch an early screening of Red last week, but (a) I'm embargoed from sharing my opinion with you about the film, (b) even if I wasn't embargoed, it wouldn't be fair to share my opinion with you when I only saw a rough cut (e.g., unfinished effects shots, temp track, color timing). Based on that rough cut, however, I can understand why Schwentke has made 20th Century Fox's shortlist to direct the Wolverine sequel (David Slade [The Twilight Saga: Eclipse, 30 Days of Night] has as well). As Schwentke proved on Flightplan and reaffirmed on Red, he knows his way around a camera. He shoots action scenes with a refreshing attention to spatial geography and coherence (Michael Bay and his imitators could and probably should take direction from Schwentke's approach to filmmaking).
We (meaning critics, bloggers, and audiences) will have to stick around for the end-credits tag to see what Willis, Malkovich, and Schwentke came up with for the new scene, but we can expect it to reflect their respective characters' backstory as CIA operatives and Willis and Malkovich's onscreen chemistry.
With rare exceptions (e.g., Iron Man), tags or buttons don't add much, if anything, story wise. Red isn't likely to be one of those exceptions. Given that likely development, what do you think of post-credits tags or buttons? Are we seeing too many of them? Not enough? Just the right amount? Feel free to sound off in the comments with your favorite tags or buttons, but please try to stay away from films released this summer (for the spoilerphobic among us).
