I've heard of Ringo Lam, he is a very big director of action movies in Hong Kong and is probably best known for a film he made there called "City Of Fire"(1989) which inspired a great deal of the plot in Quentin Tarantino's debut movie "Resevoir Dogs"(1992). He has also helmed Jean-Claude Van Damme movie "Maximum Risk"(1996) That movie I found dissapointing more so because it had a dull script where not a lot happens but the little action there was, is well done, especially a fight in an elevator between Van Damme and a big Russian thug.
I would be very pleased if he directed a Steven Seagal film.
Peace.
