Martha Jones didn't see any threat from the Carrionites because she knew that the world didn't end in 1599. However the Doctor referenced this movie when he told her about how Michael J. Fox, after he travelled back in time, did something that almost erased him from existence in the past. (DW: The Shakespeare Code)
