Variety reports that studios that are trying to fill 2010 release slates are weighing spec packages that would give them either an Adam McKay-directed action comedy starring Will Ferrell and Mark Wahlberg, or a drama that will reunite Matt Damon with his The Bourne Ultimatum scribe George Nolfi.

Damon is at the center of The Adjustment Bureau, a contemporary science fiction love story that was shopped to studios by Media Rights Capital.

Nolfi wrote a script that is loosely based on a Philip K. Dick short story, and he will make his directing debut on the film, which will begin production by late summer.

Nolfi scripted the Damon-starrer Ocean's Twelve, but they developed a closer relationship when he scripted The Bourne Ultimatum. He is also writing the fourth installment of the Bourne franchise for Universal.

Separately, several studios were bidding Tuesday on B Team, a McKay-directed action comedy that casts Ferrell and Wahlberg as cops, with Chris Henchy writing the script.

Henchy co-wrote the upcoming Ferrell-starrer Land of the Lost, and he is co-executive producer of Entourage, the HBO show on which Wahlberg is executive producer.

Even though B Team and The Adjustment Bureau come with pricey packages -- buyers essentially commit to make the movies -- both pictures are expected to have studio homes before the week is over.
