Nope. I was actually disappointed with Brom. Jeremy Irons did good for their interpretation, don't get me wrong, but I pictured someone that was a storyteller/a bard for Brom. Someone who could pull an infuriating "I know something you don't, and you're so stupid, you'll never figure it out" act while making the audience laugh. Irons' Brom just made me mad sometimes. Saphira, Gods keep her great soul, was a little old sounding, though the instinctual maturity was definitely there.
I just pictured "the last person you'd expect to be a dragon rider" as the character type for Brom. And please know that I had very little memory of Gandalf when reading Eragon, and that Brom didn't remind me of the "know it all" wizard at all.
