Six of the original leads of the "Avengers" film franchise -- Robert Downey Jr., Chris Evans, Scarlett Johansson, Chris Hemsworth, Mark Ruffalo and Jeremy Renner -- were honored with a handprint ceremony in the forecourt of the TCL Chinese Theater in the Hollywood section of Los Angeles Tuesday (23 APRIL). Entertainment reporter and historian Leonard Maltin hosted the event, coinciding with the upcoming release of "Avengers: Endgame," which filmmakers and stars have said marks the end of Marvel's "Infinity" saga, which started with the 2008 "Iron Man." "Endgame" opens worldwide this weekend
