How do you check if a WordPress template file exist?

1. So I would add to the Answer the following:

   function foo_function() {
       $located = locate_template( 'home.php' );
        if ( !empty( $located ) ) {
             // 'home.php' found in Theme, do something
        }
   }
   add_action('init', 'foo_function');
   // remember to change both of the parameters above, first one for where you want the
   // action to happen and the second one the name of the function declared
   

   As @Chip Bennett, said it will check both TEMPLATEPATH and STYLESHEETPATH, but I would append the code to a hook instead of just putting it in the functions.php file.

   But’s up to you.

2. Any reason locate_template() (Codex ref) wouldn’t work?

   if ( '' != locate_template( 'home.php' ) ) {
        // 'home.php' found in Theme, do something
   }
   

   Note that locate_template() will check both TEMPLATEPATH and STYLESHEETPATH, so it works for both a stand-alone Theme and a Child Theme.
