Saw it too, enjoyable, but without question the biggest blowjob in Canadian journalistic history. It was also made I believe as a pre-emptive defence in light of all this stuff coming out. Basically, as journalists began to uncover more details about the cash payments, Mulroney sought from a Schreiber a signed affadavit confirming that he had never given Mulroney a cent, Schreiber refused, this was the first split, then as more details came out Mulroney's spokesman told a CBC reporter that Schreiber was the "biggest fucking liar the world has ever seen." - Schreiber saw this and got so pissed off that the guy he helped so much over the years(Mulroney) had betrayed him, he basically went public with his version of things backed up by signed legal affadavits etc.
