DVD Special Features footage
In the Special Features section for the DVD version of this movie, it includes footage of Rodney Bingenheimer visiting London. There is a brief (about ten seconds) of footage showing actor Laurence Fishburne (in an unbilled cameo) walking hand-in-hand with a woman not his wife.
Fishburne is married to Gina Torres, but the woman I saw in that footage definitely doesn't look her at all.
So, who is that WASP-ish looking woman holding hands with Fishburne?
