Common cast-name mix-ups
Because *Doomsday* shares its title with other media, readers sometimes confuse its actors with those of unrelated projects. The 2008 film’s lead, actor **Mark Strong**, portrays the character **Dr. Alan G.**. Strong’s performance is distinct from the actor of the same name in other films, and his character is a scientist trapped in a subterranean facility. Another frequent mix‑up involves **Eddie Marsan**, who plays **Dr. David P.**, a fellow scientist. Marsan’s role is often mistaken for a character in a later, unrelated film due to the similarity of the name. The supporting cast includes **Ruth Sheen** as **Dr. Sarah K.**, **David Threlfall** as **Commander R.**, and **John Simm** as **Dr. J.**. These actors are credited in the official film credits and are not associated with the 2026 *Avengers* franchise.
