Only four in 10 of those questioned could recall the best picture winner -- (Iraq war film "The Hurt Locker") -- according to a poll of 700 award show viewers conducted for the Hollywood Reporter by the global research company Penn Schoen Berland.
Nearly seven in 10 viewers remembered that Bullock took home the best actress award for her role in "The Blind Side".
The poll also showed that 54 percent of viewers approve of James Franco and Anne Hathaway as Oscar hosts in 2011.
"Oscar is on his way to being more accessible, fresh and cool," said lead pollster Jon Penn.
