Yes, they are making a sequel

Braugher, Garrett Join ‘Fantastic Four’ Sequel
She’ll play Frankie Raye, which is cool for Marvel fans, but nobody else
Beau Garrett and Emmy winner Andre Braugher have been added to the cast of the 20th Century Fox and Marvel sequel “Fantastic Four: The Rise of the Silver Surfer.”
The two new additions will join the central quartet from the first film — Ioan Gruffudd, Jessica Alba, Chris Evans and Michael Chiklis — in the sequel, which is already shooting in Vancouver.
According to The Hollywood Reporter, Braugher will play a general entrusted with capturing the Silver Surfer, as the beloved character makes his big screen debut.
Garrett, meanwhile, will play scientist Frankie Raye. Marvel fans will recall that in addition to being a love interest to Johnny Storm/Human Torch, Raye had pyrotechnic powers of her own thanks to a lab accident as a child. Raye becomes Nova who, among other things, serves as a herald to Galactus.
Viewers may recognize Garrett from a stint on “Entourage,” but probably not. She’ll next be seen in Fox Atomic’s “Turistas.”
FX’s “Thief” recently earned Braugher his second Emmy, following a 1998 win for “Homicide: Life on the Street.” His recent feature credits include “Poseidon.”
