Hardman actor RAY LIOTTA is sick of playing drug addicts - because he hates using fake cocaine. Many of the intense star's most famous movies have involved coke, COP LAND (1997), GOODFELLAS (1990) and most recently BLOW (2001) among them. And the substitutes for the illegal substance often make playing a junkie particularly unpleasant, as Ray explains, "They used a laxative on Goodfellas. I remember it was really sharp going down and it wasn't at all pleasant. It really cleans you out!" (KW/LO/PDD)
