 Peter Krause (I) (qv) (Nate Fisher) originally auditioned for the  part of David, as he was impressed by the political/human rights  message that the role had and he wanted to stand up for the  character. However, the creator, Alan Ball (I) (qv) had found the  role of Nate Fisher impossible to cast, and was impressed by Krause  and his tangible chemistry with Rachel Griffiths (I) (qv) (Brenda  Chenowith).
