Hollywood loves its franchise from the Marvel Cinematic Universe to Worlds of DC, John Wick, Transformers, and beyond. At one point, Univeral was hoping to launch the Dark Universe — a shared cinematic world featuring contemporary takes on the classic Universal Monsters mythos. That seemingly included The Invisible Man starring Johnny Depp. One thing led to another and Depp parted from the film; director Leigh Whannell soon took over and according to the filmmaker, The Invisible Man was only ever developed as a standalone property rather than something that could potentially cross over with the likes of The Mummy or The Bride of Frankenstein.
