The 2001 DVD release by Warner Brothers omited a number of sound effects from the origianl Sony VHS release. The sound when characters die; when Sting attacks the Spiders in Mirkwood; Smaug's screams as he attacks Lake Town; the flapping of the Thrush's wings in all scenes; when the arrows bounce off of Smaug and when the Black Arrow pierces Smaug's belly; and the howling of the Wargs during the Battle of Five Armies.
