Venom: The Last Dance has introduced several new characters to the big-screen Marvel world, and their Knull casting repeats an excellent trend from recent comic book movies. The ending of Venom 3 saw the big bad Knull teasing future appearances, although what those appearances might be remains to be seen. With all of Venom‘s Easter Eggs and references, many suspect the villain could carry into the MCU. Whatever the case, there certainly do appear to be plans for the character, making his casting that much more significant.
