'90s TV stars: Where Are They Now?

32 of 95: Joseph Gordon-Levitt played an alien intelligence officer and the teenage son of Dr. Dick Solomon, Tommy. While he continued to appear on '3rd Rock from the Sun,' Gordon-Levitt starred in films such as '10 Things I Hate About You.' After '3rd Rock From The Sun' ended in 2001,' Gordon-Levitt graduated from Columbia University and has found much success in film.

Gordon-Levitt has starred in films such as 'The Look Out,' 'Killshot,' 'Women in Trouble,' '(500) Days of Summer,' and the 2011 sci-fi film, 'Inception.' In 2010, he toured around college campuses promoting his new site hitRECord.com. The site was started about five years ago, in 2005. The site allows members of the site (open to the public) to collaborate their work and develop art and media on the site itself. He relaunched the site after his older brother, Dan Gordon-Levitt, died at age 36 in October 2010.

In 2011, Joseph Gordon-Levitt filmed movies such as '50/50,' which also stars Seth Rogen. Gordon-Levitt is set to star as Alberto Falcone on 'The Dark Knight Rises' alongside Christian Bale and Anne Hathaway. The film is set to hit theaters in 2012.
