Well, Reed and Sue originally married in the "Fantastic Four Annual #3" book, published in 1965. Before that, they were romantically involved but not officially hitched. Marvel didn't introduce Franklin until 1968, and Valeria's arrival took an extremely long time after that - she showed up in 2002.I'm really hoping that Franklin (and even Valeria) does indeed appear in this next film, and that Susan is Susan Richards, not Susan Storm. It would be great to see something different with this family dynamic than the previous F4 films. Judging by his past work, I know that Matt Shakman can do a lot with an ensemble cast involving children.
