In the film adaptation, the origin of unstable molecules was not a deliberate invention on Reed's part, but actually mere chance; the FF's suits consisted of an all-purpose bodysuit that Victor von Doom and Susan Storm had developed to be worn under their astronaut suits while on the survey mission that resulted in the team acquiring their powers, the suits thus being exposed to the same cosmic radiation as their wearers and gaining the ability to change in the same manner.
