Yeah, Fox is too cheap, so we thought we would nod to that, and just have a glimpse of them in the background. Simon Kinberg was directing the Dark Phoenix movie in Montreal, so we shot against a green screen and the mansion in Vancouver, and then he shot separately, later in the summer, a couple of months later. The actual cast, James McAvoy and those guys, and then we melded the two and composited the two together through visual effects. It's real brief, but it always gets a laugh."
