The trailer for the uplifting horse-racing drama Secretariat has gone online.  It's an uplifting sports film/biopic based on a suburban housewife (played by Diane Lane) who ushered the horse Secretariat to the Triple Crown.  As the trailer tells us, it's based on an "impossible true story."  Just like Miracle.  And Invincible.  And The Rookie, which are all from the same producer as Secretariat.  I'm still not sure what "impossible true story," means.  The trailer makes it look like the film is trying to follow the awards success of 2003's Seabiscuit.  With these two dramatic/uplifting horse-racing dramas, I'm sure we'll be asking the question of who would win in a race between the two steeds.  The answer: I don't know. I don't follow horse-racing.

Here's the official synopsis for Secretariat:

Based on the impossible true story, SECRETARIAT chronicles the spectacular journey of the 1973 Triple Crown winner.  Housewife and mother Penny Chenery (DIANE LANE) agrees to take over her ailing father’s Virginia-based Meadow Stables, despite her lack of horse-racing knowledge.  Against all odds, Chenery-with the help of veteran trainer Lucien Laurin (JOHN MALKOVICH)-manages to navigate the male-dominated business, ultimately fostering the first Triple Crown winner in 25 years and what may be the greatest racehorse of all time.
