In an effort to draw in viewers hankering for nostalgia, CBS will broadcast two colorized versions of “I Love Lucy” starting at 8 p.m. on May 17.

The one-hour special of the classic sitcom, which starred Lucille Ball and Desi Arnaz as Lucy and Rick Ricardo, features episodes “L.A. at Last!” and “Lucy and Superman.”

“Lucy and Superman” follows the trials of scheduling kids’ birthday parties. It first aired in 1957 and features George Reeves, star of TV show “Adventures of Superman.” William Holden guest stars in “L.A. at Last!” which has Lucy and Ricky finally landing in Los Angeles because Ricky is appearing in a new motion picture. The special will also show additional material that has not been broadcast since the episode first aired in 1955.
