Banqo in a Modern Macbeth

Apparently he was in a summer theatre production of Macbeth. This version takes place in rural Afghanistan.

That is OBVIOUSLY Adam there in profile.  The problem is at the beginning of this Shutterfly album on this production- Banquo is listed as played by Tony von Halle.  I guess it was some sort of  switch but I am curious of the order. Did it start out with Adam and then Tony took the part or vice versa? I'm annoyed at all the other articles on this have Adam's name...but spelled horribly wrong. No letter D in ADAM makes for a funny looking Aam.  What kind of name is that!

see here-
"The actors are Jeff Burchfield (as Duncan), Paul Pontrelli (as Malcolm), Akeem Folkes (as Donaldbain), BrIan Richardson (as Macbeth), Renee Flemings (as Lady Macbeth), Aam Jonas Segaller (as Banquo), Danny Makali'I Mittermeyer (as Macduff), Shawn Williams (as Lennox), Mathew J, Harris (as Ross), Mia Anderson (as Angus); Wendy Snow, Erica Chambers and Regina Gibson (as The Witches), Gregory Wool (as Fleance), Kara Addington (as Mentieth) and Leigh Ellen Caudill (as Lady Macduff).
