If you are on the fence about whether a Total Recall remake is a good idea, perhaps the first full-length trailer could convince you that this is a film worth checking out.

The trailer sets up what we already know from the original: The main character Douglas Quaid (played by Colin Farrell this time around) is bored with his everyday life. When he learns about a service that implants memories, he thinks he has found a way to feel fulfilled - until a squad of troops begins shooting up the place.

In the trailer, we see Quaid "snap" and begin taking down the troops with lethality that surprises himself. Who is he really? Or are these the memories that have been implanted in his brain? After his wife (Kate Beckinsale) tries to kill him, Quaid's life unravels as he tries to answer those questions.

What's missing from the original? As it has bene reported previously, Mars isn't an important location in the film. That also means no aliens, as far as we can tell.

Total Recall is slated to hit theaters August 3.
