I had actually considered that movie myself.
What Looney Tune is that from?
It's from the 2003 movie Looney Tunes: Back in Action
. In the scene the characters are at Area 52 (Yes, 52), where they keep various aliens. In addition to the Daleks (which are the Cushing version, BTW), there are also other classic movie aliens (and Marvin the Martian, of course).
