20Ian McKellen and Patrick Stewart were offered the role of Brom
The role of Brom, Eragon’s father, and original mentor was first offered to Ian McKellen and Patrick Stewart. They both turned it down in favor of X-Men: The Last Stand in which they played Magneto and Professor X, respectively, which they were both already committed to, having starred in
the first two X-Men movies before it.
In the end, Brom was played by Jeremy Irons, who jumped at the chance to establish himself with a younger audience. Of course, Irons has taken a similar opportunity in recent years with his portrayal of Batfleck’s butler Alfred Pennyworth in the films of the DC Extended Universe.
