The movie was made and released in 2000. The movie starts '10 years ago'. About 3-5 minutes later it's 'Present Day' which is 2000. Back to the '10 years ago' area. 10 years ago is 1990 and the antique store is '???????? MacLeod Antique shop'.
Highlander 1 is New York 1985 and Highlander 3 is 1994. Both Antique stores he owned said 'Russel Nash Antiques'. Since when did he blow his cover and choose '??????? MacLeod Antique'. Plus his store gets blown up along with 'Rachel' (who he saved from Nazis in Highlander 1 special edition) in this new film on 1990 by his immortal enemy 'Jacob Kell' and all his collections are burnt to zippo. But in 1994, his stuff hasn't been burnt. Note too: Where's his adopted son 'Jack' from Highlander 3?
