The mystery behind the purpose of Golden Pantaloons, a popular infamous seemingly-useless unique item from Baldur's Gate 1, is actually reveled in Baldur's Gate II: Throne of Bhaal, the expansion pack for Forgotten Realms: Baldur's Gate II - Shadows of Amn. However, in order to find out what this item does, the player must keep it in his or her inventory throughout BG 1, import his or her main character into Baldur's Gate 2, pick the item up along with the rest of his/her BG 1 inventory in Irenicus' Dungeon, be evil towards Welther during the Buried Alive quest in BG 2, use those turned to stone in the Throne of Bhaal expansion and eventually visit Amkethran.
It has been posited on various websites that Baldur's Gate composer Michael Hoenig plagiarized the orchestration for the game track "Attacked by Assassins" from Henry Mancini's original orchestrated theme to the film Lifeforce (1985). No formal allegations have been made but if one compares the two tracks the similarities between the music from the 1998 game and the 1985 film is incredibly striking.
