From Disney:

Hilarity reigns in this all-new movie starring Timon and his windy pal Pumbaa -- and featuring the new song "That's All I Need"! Now, in THE LION KING 1 1/2, see how things really happened -- according to their perspective -- in this rip-roaringly funny story within the story of THE LION KING. Find out the truth about some "passed" events -- such as when King Mufasa introduced his young heir to the animal kingdom. Let's just say there was something behind that dramatic moment when all the animals bowed to their new ruler! In this all-new comedy-adventure, Timon and Pumbaa reveal the true hullabaloo behind their departures from their meerkat and warthog 'hoods. Tag along as the two buddies from the brush search for their dream home, share their joys and trials as they raise young Simba using the "Hakuna Matata" philosophy, then cheer them on as they help Simba save the Serengeti and reclaim his place atop Pride Rock. Nathan Lane, Matthew Broderick, and the original voice cast return for this all-new hysterical musical tale -- and meet colorful new characters like Timon's Ma and Uncle Max! Get ready for some king-sized fun with Timon and Pumbaa, the greatest unsung heroes of the savanna. They were there . . . and they ain't LION!

This doesn't sound too appealing. I probably won't be picking it up but I might give it a rental.
