In one of the biggest surprises of Super Bowl Sunday, Netflix abruptly Heroes). Pegg voices a radio news reader, while Grunberg voices the Cloverfield space station's NASA , Joe.
The film is set in the year 2028, when the entire planet is suffering from an energy crisis and on the brink of war as countries' fuel shortages are depleted and they grow ever more desperate to survive. Humanity's only hope is the space station, which is equipped with a powerful particle accelerator that - if the crew can get it working - will provide unlimited energy. However, some down on Earth believe that firing the particle accelerator risks ripping a hole in space and time, which could have catastrophic results.

Grunberg has a long history of working on Abrams projects - one that stretches back over two decades. He appeared in the TV series Felicity (which Abrams co-created with Cloverfield director Matt Reeves), as wall as Abrams' other late-90s/early-2000s show Alias. He played an ill-fated pilot in Lost, and also had roles in Mission: Impossible III, Super 8, and both the Star Wars and Star Trek franchises.
Pegg and Abrams first worked together on Mission: Impossible III, where Pegg made his debut as IMF technician Benji Dunn (he's stayed with the series since, and this year will star in Star Wars: The Force Awakens. You can hear Pegg's voice cameo right at the start of The Cloverfield Paradox (he actually has the first line of dialogue), reading a report about the Cloverfield space station and the Shepard Particle Accelerator.
Grunberg's character recurs throughout the movie. He plays Joe, the Cloverfield crew's communications at NASA's Marshall Space Flight Center in Huntsville, and speaks to both the astronauts and to Ava Hamilton's (Gugu Mbatha-Raw) husband, Michael (Roger Davies). As the story progresses, Joe's job gets more and more stressful... but we can't say more without spoiling the movie.
