I remember watching a film when I was young... it would have been in the 90s, and it had fairies in it. There were normal sized people too, but there were two fairy clans at war and the two main ones fell in love. It was really tragic because they had to kill themselves in the end by using a special 'cordial'. The whole thing was very romeo and juliet... if anyone knows what film I am talking about could they PLEASE let me know? I'm getting desperate here...

The only thing that comes to mind that is exactly like this is The Magical Legend of the Leprechauns (1999) (TV) (http://www.imdb.com/title/tt0205214/)...

American businessman Jack Woods rents a cottage on the enchanted Emerald Isle which is occupied by a family of leprechauns. Leprechaun Seamus Muldoon's son and son's friends crash the fairies' costume ball and Muldoon's son falls in love with fairy Princess Jessica. Their love re-ignites a feud between the leprechauns and the fairies, which escalates into a war. The Grand Banshee warns of terrible consequences and Jack Woods is chosen to make peace. Woods interrupts his own romance with an Irish beauty to help, and becomes involved in a strange and wonderful magical adventure.

It was a Halmark movie.

Thanks so much. I just researched the leprechaun film and I'm pretty sure that's the one!
