There's an adage in playwrighting and screenwriting that "Comedy is tragedy plus time." (Comedy stars Carol Burnett and Steve Allen, before her, are credited with the quote.)

It's been about a decade since the Great Recession, the 2007-08 financial crisis, so it's about time somebody made a motion picture comedy about it.What's unexpected is that the movie would be directed by Adam McKay, who cowrote screenplays and directed Will Ferrell to box-office and comedic success in lighter fare such as "Anchorman: The Legend of Ron Burgundy" (2004), "Anchorman 2: The Legend Continues" (2013), "Step Brothers" (2008) and "Talladega Nights: The Ballad of Ricky Bobby" (2006)."The Big Short," with a screenplay by McKay and Charles Randolph ("Love & Other Drugs," 2010), is based on "The Big Short: The Doomsday Machine" (2010) by Michael Lewis, a nonfiction book about the financial crisis."The Big Short" is chockablock with financial terms. There are so many, it may make your head spin. With that in mind, McKay has many of the actors, as well as celebrities who appear randomly in cameos as themselves (Margo Robbie, Selena Gomez, Anthony Bourdain), talk directly to camera (addressing the audience) with explanations of arcane, but important, financial terms.In "The Big Short," several investment advisers (real names are changed or only first names are used), believe there's a housing bubble, so they bet against mortgage-backed products, predicting, correctly it turned out, that these products will fail.At the center of the unraveling is Michael Burry (Christian Bale), who sits at his computer listening to hard rock as he analyzes the products being marketing by financial institutions. He's convinced that he's uncovered a house of cards in what became the U.S. mortgage housing crisis of 2005. While he was at first roundly ridiculed, his taking a short position yielded he and his investors something like a $269 million profit.Mark Baum (Steve Carell) and his financial-investor team investigates Burry's claim, traveling to Florida to see firsthand the effects on homeowners who recently took out loans and to meet mortgage company agents who make the loans. They also travel to Las Vegas to attend an American Securities Investors convention.Ben Rickert (Brad Pitt) is a retired investor who's coaxed back in by two young investors convinced that betting in favor of a financial collapse will yield profits.Presiding over the proceedings is Jared Vennett (Ryan Gosling), a banker whose cynicism persuades the other protagonists to take their negative positions.The dialogue in the screenplay by McKay and Randolph is highly colorful in its preciseness. McKay's direction keeps the story popping.Pitt is fine as the bearded, sage investor. Gosling is again a revelation in yet another nuanced performance as a tough-as-nails investment honcho.Bale proves yet again the chameleon in an intense, turned-inward performance as the genius financial analyst.Carell shows why he's one of the most intriguing actors as he again segues with ease into another dramatic role (following his Oscar actor nomination for his chilling turn in "Foxcatcher" (2014)."The Big Short" is a must-see. You might want to consult your financial adviser afterward or, better yet, have him or her accompany you to the screening."The Big Short," MPAA Rated R (Restricted.
