"No Country," from Ethan and Joel Coen, won a handful of top Oscars Sunday, including best director, best supporting actor and best adapted screenplay.

Historically, films winning best picture can see significant upticks in box office business--if they are still in theaters, that is. In each of the last two years, the winning film was done with its theatrical run by the time of the Academy Awards ceremony.

"No Country' could potentially add $10 million to $20 million to its domestic cume, which was $64.3 million through Sunday, according to Rentrak. Film, along with the other four best pic contenders, enjoyed a box office boost between the announcement of Oscar noms on Jan. 22 and Sunday's kudocast.

Last weekend, "No Country" was up a hefty 28%, indicating its status as frontrunner.

"No Country," produced by Scott Rudin, is a co-production between Miramax and Paramount Vantage. Miramax is distributing domestically; Vantage, overseas.

Following a traditional platform release pattern, "No Country" debuted in 28 theaters on Nov. 9. By Dec. 14, it had expanded to 1,348 locations--it's widest point to date.

After that, Miramax began shedding screens, before expanding out again once Oscar noms were announced.
