Zeta-Jones knits on film set

Catherine Zeta-Jones cannot bear to be parted from husband Michael Douglas while he works on his new film.

Douglas is producing and starring in spy movie The Sentinel, and Catherine cannot resist paying visits to the set.

The actress keeps herself busy on the set by knitting for hours at a time.

"She's a great knitter - she comes and hangs out and does her knit one, purl two thing!" Douglas told the Daily Star.
