Description Of First Indiana Jones IV Trailer?

Quicksand? Stairs coming out of walls right out of an M.C. Escher work? A box labeled Roswell? Shia cracking teacher jokes to Ford? Is this what we can expect from the first trailer for Indiana Jones and the Kingdom of the Crystal Skull that will be attached to The Spiderwick Chronicles on February 15th? The following description is from a spy over at AICN...

The trailer starts off with the Paramount logo, then shows the idol from the start of RAIDERS.

Words comes across the screen and say, "He found the Ark..."

Then clips from TEMPLE OF DOOM as it says, "He survived the Temple..."

Then clips of the third movie and, "He saved the Grail."

Then it shows a clip of a car pulling up and Indiana being thrown from the car. Then it says, "On May 22nd... he is back," and it shows him picking up his hat and the silhouette of Indiana Jones. Cue theme song.

Some really fast action scenes follow, and the highlight is a car chase scene in the warehouse where RAIDERS ends. One quick shot shows a box that is labled "Roswell". The trailer shows Cate Blanchett with dark hair ordering around troops.

The teaser then shows what looks to be a huge Mayan temple where the actors fall through quicksand, and the temple opens up and they start running down a long staircase where the stairs are coming out from the walls.

After some more quick action scenes, the trailer ends with Shia Labeouf standing at the bottom of stairs and looking up to Harrison Ford. Shia says, "I thought you said you were a teacher?!?!"

After two quick scenes where Indiana is punching a guy, it cuts back to Harrison and he replies, "Part time!"

I wasn't expecting much, but I was more than surprised and pleased with what I saw.

If this is not what the trailer plays like, it's a bit of hilarious guessing. If it is legit, sounds playful, a little cornball and just enough to set fans' anticipation a fire.
