Dated Natalie Portman. [July 2001]

Lukas enjoyed ice skating (hockey) and turned up on occasion at the ice rink at Northcross Mall in Austin (1986-1988). He was a good skater, by the way, and the employees were quite fond of him.

Eleven years after playing the title role in Witness (1985), opposite Harrison Ford, he appeared in Mars Attacks! (1996). At the end of the film, he receives a medal, just as Ford did in Star Wars (1977). Ford received the medal from Carrie Fisher, playing Princess Leia. Haas received his from Natalie Portman, who would go on to play Princess Leia's mother, Queen Amidala.

Drummer and pianist for a band called the Rogues

Son of Emily Tracy.

Good friends with Leonardo DiCaprio.

Brothers are fraternal twins named Simon and Nikolai Haas. Like Lukas, they are also musicians.
