No matter what happens at the Academy Awards Sunday night, best actress nominee Sandra Bullock is a winner this weekend – although not necessarily in the way aspiring young actors might dream of.

Bullock, who drew raves for her performance in “The Blind Side,” was honored twice Saturday night for something else altogether at the 30th annual Razzie Awards, which good-naturedly tweak Hollywood every Oscar weekend for all the films it cranked out the previous year at the other end of the quality spectrum.

In Bullock’s case it was “All About Steve,” the comedy that cast her as a lovesick stalker and earned her honors as worst actress and worst screen couple (with Bradley Cooper).

It could have been worse for Bullock, though. “All About Steve,” which she helped produce, also was nominated as worst picture but that (dis)honor went instead to “Transformers: Revenge of the Fallen,” which wound up as the night’s big winner (or loser, depending on your point of view), collecting Razzies for worst director (Michael Bay) and worst screenplay (Ehren Kruger, Roberto Orci and Alex Kurtzman).

In ceremonies at the Barnsdall Gallery Theatre in Hollywood, other awards went to siblings Joe, Kevin and Nick Jonas, who collectively were named worst actor for “Jonas Brothers: The 3-D Concert Experience”; Sienna Miller for her supporting role in “G.I. Joe: The Rise of Cobra”;  Billy Ray Cyrus for his supporting role in “Hannah  Montana: The Movie”; and “Land of the Lost” for worst prequel, remake, rip-off or sequel.

The Razzies are presented by the Golden Raspberry Award Foundation based on ballots sent by founder John Wilson to 657 journalists, industry workers and fans.

“Avatar” picked up another award Tuesday night, but Oscar prognosticators probably shouldn't read anything into it -- “The Hurt Locker,” "Up in the Air" and “Inglourious Basterds” weren’t eligible.

James Cameron’s blockbuster was named best live-action 3-D feature by the month-old International 3D Society, kicking off its inaugural Lumiere Awards at Grauman's Chinese Theater in Hollywood.

“Up,” also in the running for Academy Award best picture honors, was honored as best animated 3-D feature, and another Pixar work, “Partly Cloudy,” won in the category for best short 3-D motion picture/narrative.

The International 3D Society was formed Jan. 21 with a stated mission of advancing “the achievement of professionals working in the arts and technologies of Stereoscopic 3D.” Its board of governors includes a diverse group -- studio executives, the heads of 3-D and post-production houses and even a PhD at UC Berkeley's school of optometry. The awards were voted on by more than 100 film industry 3-D experts, a spokesman for the group said.

Among other winners Tuesday were the Imax film “Under the Sea 3D” as best 3-D documentary, “G-Force” as best 2-D-to-3-D converted feature, and “Avatar’s” Neytiri (played by Zoe Saldana) as best 3-D character of the year.
