Here's why:
* Many movies involve characters being tied up: This is a common trope in thriller, horror, and action genres. It's very possible Catherine Zeta-Jones has been in a film where her character was tied up, but we need more information.
* "Tied up" can be metaphorical: Sometimes, the phrase "tied up" is used to describe a character being trapped or in a difficult situation. It doesn't always mean literally being bound.
* You might be thinking of a specific scene: If you remember a scene where Catherine Zeta-Jones was tied up, it might be easier to find the movie if you can describe the context or the other characters involved.
To help me answer your question, please provide more information:
* What movie are you thinking of?
* What was the context of the scene?
* What other characters were involved?
Once I have more details, I can try to identify the movie and confirm if Catherine Zeta-Jones was indeed tied up in it.
