Zarkorr! The Invader

Intelligent aliens who have been studying Earth for centuries decide to challenge mankind by sending in a 185-foot, laser-eyed monster to wreak city-crushing havoc. Only one incredibly average young man, postal worker Tommy Ward (Rhys Pugh), can find the beast's weakness and save the planet--with a little help from a 5-inch-tall female hologram.
