A cast member doesn't match the credits of the film

Recently I looked through the credits for Norwegian actor Per Aabel, and to my surprise I noticed he was credited for playing a small role, 'rich woman', in the American film Twenty Bucks (1993). I thought this sounded a little strange so I ordered a DVD copy of the film and watched the whole thing yesterday. While it is plausable that he did in fact do this role, the credits of the film attributes the role to a person named 'Trudye Bremner'. So now I'm trying to understand if this was indeed Per Aabel, just credited under a pseudonym, or if someone has credited Per Aabel as a joke. I'm a little stumped. What does the community think?

If it is indeed Per Aabel, I guess that means we need to add something to the attributes field to show that he is credited under a pseudonym.
