MovieHole picked up some quotes from writer/director Sheldon Lettich (Double Impact) who is still friends with Jean-Claude Van Damme and is working on Double Impact 2 with him. He mentions the action star is leaning towards making Expendables 2. Jean-Claude famously turned down a role in the first film and has since regretted his decision. He also says that the involvement of Steven Segal could be an issue for Expendables producer Avi Lerner who has a bad history with Segal.
“JC seems to be leaning towards appearing in the sequel, as far as I know. If Steven Seagal is not in the sequel, from what I’ve heard it won’t be because of Sly but because of producer Avi Lerner, who had a few bad experiences with Steven.”
While Jean-Claude's last decent film that was playing in theaters was 1996's Maximum Risk. He's been able to make some decent films such as the dramatic turn in JCVD and solid return to action with Universal Solider: Regeneration. I believe like Arnold Schwarzenegger, Van Damme has a limited amount of action roles left in him and Expendables 2 could be a great end to his career in the genre.
