Not really...
What you really want to do is open the image of the jedi fighter in Photoshop or similar and look at its sizes of height and weight in cm's.
Go back to Maya and create a poly plane to match those sizes. Ensure you check that Mayas sizes are set to cm first (it should be the default).
Once you have created that plane then apply the image to it, it should match without any need to ammend of apply a UV map to it.
