CAPTION: Jennifer Garner, Rob Lowe and Ricky Gervais star in “The Invention of Lying.”

The Invention of Lying (Warner, Blu-ray or standard DVD, PG-13, 99min.). Co-written and co-produced by star Ricky Gervais (host of The Golden Globe Awards, co-creator of the British “The Office”), the film is funniest at the beginning when we are introduced to a world much like our own, except that no one lies. Everyone tells the truth, no matter how harsh. Fiction literature does not exist and films are spoken lectures about history.

Mark Bellison (Gervais) is a screenwriter whose milieu is the 1300s and thus his most recent script is called “The Black Plague.” Universally loathed at work, but especially by fellow screenwriter Brad Kessler (Rob Lowe), he is due to be sacked by his boss (Jeffrey Tambor). He does, however, score a date with his dream girl Anna (Jennifer Garner), although she tells him upfront that nothing will happen because she wants beautiful kids and he is genetically unsuitable. Unable to come up with $800 for his rent, Mark goes to the bank to withdraw his $300. The bank system is momentarily down, so he says he wants to withdraw $800, and thus the successful lie is born, because no one can imagine anyone being untruthful.

When Mark is told is mother is dying, he paints her a lavish, happy picture of the afterlife. That is overheard and soon is being spread everywhere, including on the TV news. Asked for more details, Mark, in effect, invents religion, using two pizza boxes (the film is heavy with blatant, but often funny, product placement) as his tablets of pronouncements. Of course, at this point too, the film starts to run out of steam.

Look for many, many cameos, the funniest of which is Edward Norton as a traffic cop with a cocaine habit. Extras include a caveman prequel, featuring much of the film’s cast; five deleted scenes; outtakes; four podcasts; a making-of-feature; and a look at the film’s co-creator Karl Pilkington, also co-host of “The Ricky Gervais Show.” Grade: film 2.75 stars; extras 2 stars

Gamer (Lionsgate, Blu-ray or standard DVD, R, 95 min.). From writers/directors Mark Neveldine and Brian Taylor (the two “Crank” films), this is quite the noisy, violent mess. Gerald Butler plays Kable (real name Tilman), an inmate who has volunteered for the virtual game “Slayers.” If he runs 30 successful missions, he will be released and then he can reunite with his wife (Amber Valetta as Angie) and young daughter. Kable is operated by a 17-year-old Simon (Logan Lerman), while Angie is an avatar of a male flat slob in the earlier-developed “Society” game (think Day-Glo “Sims,” ramped up in weird fashion and sexual perversity).

The kingpin behind both games is Ken Castle (Michael C. Hall, who gets to bare his chest in a fisticuffs showdown with Kable; and sing and dance along to Sammy Davis Jr.’s “Under My Skin,” one of the most bizarre moments in recent film history yet endearing, even if he is totally out of left field). Kable convinces Simon, once he can communicate with him, to let him go and he escapes the cape (the game is nothing but random violence, totally without plot) and hooks up with some freedom fighters.

The film is ambitious, but incoherent. The Blu-ray sound wears out the rear speakers and is very amped up. While there is audio commentary by the directors and actors Valletta, Alison Lohman and Terry Crews, and a 70-minute making-of look, the directors give most of their energy to explaining their use of the new Red camera system. Grade: film 2 stars; extras 2.5 stars

Whiteout (Warner, Blu-ray or standard DVD, R, 101 min.). This adaptation of a graphic novel by director Dominic Sena is tedious at best. Even the scenes of snowy, icy isolation (Manitoba standing in for Antarctica) fail to truly impress, even on Blu-ray. Kate Beckinsale (the “Underworld” films) plays U.S. Marshal Carrie Stetko, assigned to the Amundsen-Scott base after a Florida drug bust went horribly wrong (we see part of this far too often in flashbacks; the film has way too many flashbacks). The body of a murdered man shows up, then others and a downed Russian plane from 50 years (the prologue) is found. There is absolutely no suspense here: non-action scenes, like the discovery of the contraband, are stretched out far too long; and outdoor fight scenes are staged in such a way as to make it difficult to keep track of who is who.

DVD extras include two deleted scenes; a making-of feature; and a page-to-screen feature. Grade: film dog; extras 1.5 stars

Rating guide: 5 stars = classic; 4 stars = excellent; 3 stars = good; 2 stars = fair; dog = skip it
