You are right Spiro, I think that he could be in South Africa filming Strike Back (possibly)...but no inside information, just speculation.
BTW I'm watching Who do you think you are? with Spike Lee..I love this programme, completely addicted. It's the American version, but still... They are showing The 25th Hour movie he directed afterwards, which is an excellent movie with Ed Norton. One of the first post-911 movies.
My daughter is 6 - 7 in April, so I guess she is in the year above yours (currently Year 2).
