Yeah, he's nowhere to be seen in
G.I. Joe: Retaliation or
Olympus Has Fallen. I suffered through both and never saw him.
In
Uncommon Valor, he's credited as Blaster's Assistant. I think he
might be the person who takes a bag from Blaster (Reb Brown) at the airfield and loads it onto the plane. We only see the guy from behind, never even a hint of his face, but as familiar with Dudikoff as I am, I think it could be him. He might have had more screentime with Brown that ended up getting cut out late in post-production and that's how he ended up still being credited.
Haven't seen
Bloody Birthday, but the site's review did include a screenshot with him in it.
And here he is in
Tron. The only scene he appears in.
