Watch Danny Trejo Kill Justin Bieber In 'Machete Kills Again... In Space'

'PYD' singer stars as a C3PO-meets-R2-D2 hybrid named Bleep in the campy preview.

Is Justin Bieber making his acting debut in a "Machete Kills" sequel? Well, no, but a robotic version of him is.

The mock trailer for "Machete Kills Again... In Space" goes the "Gravity" route, taking Robert Rodriguez's campy characters to — you guessed it — space. The trailer, which debuted last month in theaters alongside "Machete Kills," is decidedly "Star Wars"-esque, even (stunt) casting the "PYD" singer as a C3PO-meets-R2-D2 hybrid called "Bleep." Needless to say, Machete doesn't take kindly to him.

Lady Gaga, who actually did make her acting debut as La Camaleon in the 2013 action comedy, also appears in the trailer. Offering a sultry stare into the camera, a voiceover declares that the pop star will be playing "whoever she wants to be."

Michelle Rodriguez and Alexa Vega also appear to reprise their roles in the spoof, slicing and dicing their way through outer space.

Could "Machete Kills Again... In Space" ever come to fruition? Maybe. The "Machete" franchise itself was born from a faux trailer that played in 2007 as part of Rodriguez's collaborative project "Grindhouse," which also included fake trailers and segments from Eli Roth, Quentin Tarantino, Edgar Wright and Rob Zombie.

For now, Rodriguez is hard at work finishing "Sin City: A Dame to Kill For" alongside Frank Miller. The action sequel hits theaters August 22, 2014.
