Verisimilitude

"An illusion's verisimilitude helps to trick us into seeing what isn't really there. Verisimilitude is the appearance of being true or real, and is something that we tend to all strive for in our daily lives. The word is often used to describe stories, so next time a friend tells you an epic story about their night, be sure to let them know whether or not their story had verisimilitude." (Brainjet.com)

The verisimilitude of his acting is astounding!
