If you're looking forward to the release of the fourth installment of the Indiana Jones series, Indiana Jones and the Kingdom of the Crystal Skull, on May 22nd, you might want to tune into the History Channel on Sunday, May 18th.

They are showing a two-hour special called "Indiana Jones and the Ultimate Quest," which appears to focus on the impact that the movies have had on public perception of history and archaeology, and the fact that they have inspired more than a few people to get their hands dirty in the field.

Here is the synopsis from the History Channel web site:

Throughout history there have been legendary artifacts that have captured the imagination of adventurers everywhere. While belief in their existence seems to fly in the face of reason and science, there have been those who have devoted their lives to their discovery. One man has looked for some of these remarkable treasures. He is Indiana Jones--professor of archeology and an adventurer who has uncovered some of the world's greatest mysteries. But Dr. Jones is just a fictitious character and it's widely assumed that the artifacts he searched for were also figments of a writer's imagination. But were they?

The first airing is at 7pm Central Time (8pm Pacific) on May 18th, and it is repeated later that night and then again on May 31st.

According to DirecTV's online programming guide, the show is available in High Definition on The History Channel HD.
