"Hawaii Five-0" actor Scott "Danno" Caan resumes filming tomorrow, after taking an L.A. breather to tend to a problematic knee. "Working with McGarrett (Alex O'Loughlin), you're bound to get bumps and bruises along the way," said exec producer Peter M. Lenkov about the risks. Thus, the proactive medical attention, since Caan does his own stunts.
