Actually, I watched this movie about 2 or 3 weeks back. Based on a novel and starring the talented Leonardo DiCaprio, Tobey Maguire, Carey Mulligan, Joel Edgerton and Isla Fisher, the movie tells a tale of love set in the year 1922.
The protagonist was alcoholic Nick played by Tobey, who moved in next to the mansion of the mysterious Jay Gatsby played by Leonardo, who threw regular extravagant parties even though none of the guests had met Gatsby themselves. As the story unfolded, Nick learnt that Jay did all the things he did for one thing - to get re-acquainted with his love Daisy, whom he first met in 1917 but was later already married and lived on the other side of the bay.
The ending is a tragic one and all the actors and actresses put up a good performance to pull this movie off.
One other notable thing worth mentioning are the songs performed by Lana Del Rey, which were hauntingly apt for the movie and beautiful and I attached below the theme song "Young and Beautiful".
