That’s the official name of FF2 according to Superhero Hype:
In the sequel, the enigmatic, intergalactic herald, The Silver Surfer, comes to Earth to prepare it for destruction. As the Silver Surfer races around the globe wreaking havoc, Reed, Sue, Johnny and Ben must unravel the mystery of The Silver Surfer and confront the surprising return of their mortal enemy, Dr. Doom, before all hope is lost.
Doug Jones (Ape Sapien in Hellboy) is rumored to be playing the Silver Surfer.
Then does this mean that Galactus will be showing up? You can’t have a Silver Surfer without a Galactus…
Well…sounds interesting enough. I’m bittersweet about Doom though. I really don’t think he was needed, and if Galactus is in there, it’s gonna be a very crowded movie.
Well, if Doom’s there then maybe he steals the Surfer’s Power Cosmic, goes crazy with power, then Galactus shows up without the Surfer there to save humanity! Uh oh…
