This week marks the beginning of the end for “Harry Potter” fans, as part one of the saga’s finale, “Harry Potter and the Deathly Hallows,” will be released this Friday.

You can get your fill of “Potter” stars on late night TV Monday, with Emma Watson appearing on the “Late Show with David Letterman” and Daniel Radcliffe on “Late Night with Jimmy Fallon.”
