Reese Witherspoon revealed she does not have fond memories of filming her sex scene with Mark Wahlberg for the 1996 psycho-thriller "Fear." "It wasn’t explicit in the script that that's what was going to happen, so that was something that I think the director thought of on his own and then asked me on set if I would do it, and I said no," she said about the James Foley-directed film. "It wasn't a particularly great experience."
