Defining Post for Facebook (share)

Well, I cannot get this to work. I only want a Facebook-Share-Button, but I have no control over what's showing on FB. I CAN share the link, but I would like to specify:
URL, Title, Description, Image(!)

Whenever I set the url (tried addthis:url="http://www.beamer-verleih.com") OR I specify this in the metatags :
<meta property="og:image" content="http://www.beamer-verleih.com" /> )

... FB will automatically override everything else I set up in the og-Metatags. and pick the image/description and so on from the url (which I do not want).
-???

example:

<meta property="og:title" content="Cut the Rope5" />
<meta property="og:type" content="game" />
<meta property="og:description" content="Another good description for this." />
<meta property="og:image" content="http://www.cuttherope.ie/fb.png" />
<meta property="og:site_name" content="Cut the Rope55" />
..will work

<meta property="og:title" content="Cut the Rope5" />
<meta property="og:type" content="game" />
<meta property="og:description" content="Another good description for this." />
<meta property="og:image" content="http://www.cuttherope.ie/fb.png" />
<meta property="og:site_name" content="Cut the Rope55" />
<meta property="og:url" content="http://www.cuttherope.ie/" />

..will display grab anything it finds on http://www.cuttherope.ie and forget about title/description/image...
