The first five episodes of WandaVision are now available to watch on Disney+ and the latest two featured Kat Dennings as Darcy Lewis. This marks Dennings' first time in the Marvel Cinematic Universe since Thor: The Dark World was released in 2013. Dennings is rejoining the MCU during one of its most ambitious projects. In fact, she recently told Extra TV that she thought the idea was "insanity" when she first heard the pitch.
