(Anchor Bay Entertainment) Imagine that you would see Channing Tatum, Anthony Mackie, Chris Pratt, Kate Mara, Rosario Dawson and Justin Long at your 10-year high school reunion instead of that weird cheerleader who kept Beanie Babies in her locker. You’d probably be more inclined to show up, I’m guessing.

Anchor Bay Entertainment — the studio behind the upcoming dramedy ”10 Years” — is hoping that impulse translates into movie ticket sales, as their film stars all of the aforementioned actors as former classmates reassembling for, yes, their high school reunion.

Added bonuses: Aubrey Plaza is in this, too, though not in a “Parks and Recreation”-esque role as the significant other of Pratt. (She’s married to Brian Geraghty of “The Hurt Locker” and “True Blood” instead). So are Scott Porter, aka Jason Street of “Friday Night Lights” fame, and Tatum’s real-life wife Jenna Dewan-Tatum, playing his fictional girlfriend in the movie.

Check out the trailer, which debuted today on Yahoo!, below, then start figuring out what in the world you can possibly wear to a 10-year high school reunion movie in which you might run into Channing Tatum. (It’s

Robert Downey Jr.: recovering after injury on set. (Matt Sayles - Invision/AP)

Robert Downey Jr. was injured Wednesday on the set of “Iron Man 3” in Wilmington, N.C. But don’t worry. The man New York Magazine dubbed the most valuable star in Hollywood is going to be fine.

As People reports, Marvel Studios released a statement today confirming that Downey is recovering from an ankle injury sustained while he was performing an unspecified stunt. (I’m assuming said stunt involved zooming into the stratosphere like a total boss, but that information has not been confirmed, as it exists solely in my imagination, and also the clip below from “Iron Man.”)

Don’t roof rack them, bro. (John Hayes - AP)

As noted in yesterday’s Celebritology morning mix as well as the In the Loop blog, Devo is releasing a new song dedicated to Seamus, the family dog that famously once was strapped to the roof of presidential candidate Mitt Romney’s station wagon

The track by the new wave pioneers, called “Don’t Roof Rack Me, Bro,” has made its debut on Rolling Stone’s Web site. And all politics aside, I have to admit that it is kind of catchy, in a twangy, contemporary-meets-retro-novelty-song kind of way.

Oprah Winfrey recently traveled to Barbados to have a sit-down with Rihanna in what, based on a clip from the interview, appears to be a villa very similar to the one occupied by Angela Bassett in “How Stella Got Her Groove Back.” (Look at the water behind them. It’s so ... aquamarine.)

First Look: Rihanna Opens Up About Chris Brown

Actually, the just-released video (see above) isn’t a breezy conversation by the sea. It shows us one minute and 19 seconds of Rihanna discussing the aftermath of her 2009 assault by ex-boyfriend Chris Brown, with tears in her eyes and, arguably, more raw emotion than she displayed when she first discussed the sad episode with Diane Sawyer a few months after it happened.

A morning mix of entertainment headlines...

Mayim Bialik — one-time star of “Blossom” and current portrayer of Amy on “The Big Bang Theory” — is recuperating after a car accident that happened Wednesday. People reports that a car filled with tourists from Chile crashed into Bialik’s vehicle on Hollywood Boulevard in Los Angeles. She was transported to the hospital with a serious injury to her left thumb but appears to be recovering well. Her husband tweeted on her behalf to tell her Twitter followers that she won’t have to lose that thumb. (People)

Universal Pictures says Kristen Stewart has not been dropped from the sequel to ”Snow White and the Huntsman,” according to The Wrap. “We’re currently exploring all options to continue the franchise. . . . Any reports that Kristen Stewart has been dropped are false,” Universal co-chair Donna Langely told the Web site. That contradicts a story by The Hollywood Reporter and noted in yesterday’s morning mix, which said Stewart had been dropped from a planned sequel and that the next movie would be focused on Huntsman Chris Hemsworth. Universal now says there still may be a Huntsman spinoff, but that doesn’t mean Stewart is no longer the fairest of them all. Man, this reminds me of that time when it seemed like Stewart had been cast in “Lie Down in Darkness,” and then it turned out she had not been yet. (The Wrap)

Chris Brown and Drake have been sued for $16 million for that nightclub fight back in June in which their respective entourages reportedly threw glass bottles at Manhattan’s W.i.P. The lawsuit was filed by Entertainment Enterprises, the company that owns the trademark for Greenhouse, which — stay with me now — shares space, owners and a liquor license with the W.i.P. club, according to the New York Post.

Roger Sterling is joining the cast of “Arrested Development.” John Slattery, who plays the ad exec with a pocket perpetually full of cash on “Mad Men,” will be in multiple new episodes of the Bluth family comedy, TV Line reports, but who he will play remains unclear. May I suggest Franklin’s long lost, non-puppet uncle? (TV Line)
