mod_rewrite help needed

I need to have the following URLS rewrite to one PHP script.
I'm converting static pages to a dynamic php script.

www.mysite.com/blue/widgets-large-0993.htm
www.mysite.com/anysub/any-other-product-widgets-093.htm
www.mysite.com/red/big-widgets-small-9923.htm
www.mysite.com/red/big/lovely/greet-widgets-for-boats-9923.htm

Where ANY url containing "widgets" would forward to
www.mysite.com/myscript.php

I've tried many options:

RewriteEngine on
Options +FollowSymlinks
RewriteBase /
Rewriterule ^.*WIDGETS$ myscript.php?id=uri=%{REQUEST_URI} [L]

Does not work.

something like this?


RewriteEngine on
RewriteBase /var/www/some/path/
RewriteRule ^widgets.htm$ myscript.php

RewriteEngine on
RewriteBase /
RewriteRule ^(.*)widgets(.*)$ /myscript.php?id=uri=%{REQUEST_URI} [L]
