Heath Ledger and Jake Gyllenhaal's steamy clinch in Brokeback Mountain has been named the best screen kiss of all time. The man-on-man cowboy action beat off stiff competition from Audrey Hepburn and George Peppard in BREAKFAST AT TIFFANY'S, and Brad Pitt and Angelina Jolie in Mr And Mrs Smith. Same-sex smooch fans voted Selma Blair and Sarah Michelle Gellar's kiss in Cruel Intentions into fifth place, according to the poll carried out by online DVD rental site Lovefilm.com.
