Fellow celebrities like Jason Bateman, Sam Rockwell and Marisa Tomei have also revealed what they are currently obsessed of.
Scottish actor Alan Cumming has launched a new website which encourages fans to share their obsessions. The "X2" star has set up Itsasickness.com which features postings about a variety of topics, including unusual hobbies, favorite TV shows, pets and music.
In a video message posted on the site, Cumming says, "I'm Alan Cumming and I have a question for you. What's your sickness? What are you obsessed with? What do you geek out about? That is your sickness. This is where I geek out. Come on over and see who is obsessed."
Cumming has enlisted the help of his celebrity friends to initiate groups on the site, encouraging members of the public to join in the discussions. Jason Bateman has shared his penchant for classical music, insisting he is "obsessed" with it, and Sam Rockwell has professed his all-consuming love of acting, while Marisa Tomei admits to being a life-long fan of hula hoops.
She says in a video post, "It's round, it's pink, it's hypnotic and it's pretty. You get like really cool bruises over your body, in nice little places. People generally get happy because it reminds them of a childhood memory."
