Not to be mistaken for the next Garry Marshall celebrity fest, The Big Wedding does indeed star New Year’s Eve supporter Robert De Niro (whose recent career can only make a man weep), this one is instead directed by Justin Zackham, writer of The Bucket List. Following a wedding of the larger capacity, the film follows a family whose patriarch and matriarch must pretend they are in love in order to please their adopted son.

Don’t worry, it isn’t as complex as it sounds from this first trailer. In fact, it seems like the lowest-denominator romantic comedy one could get. We’ve got heavy slapstick, cheap jokes and usually great actors going through the motions — all the necessary factors guaranteeing a healthy box office. Check out the trailer below via Apple, along with the official poster, for the film also starring Diane Keaton, Susan Sarandon, Robin Williams, Katherine Heigl, Amanda Seyfried and Topher Grace.

Synopsis:

With an all-star cast lead by Diane Keaton, Robert De Niro, Susan Sarandon, Robin Williams, Katherine Heigl, Amanda Seyfried and Topher Grace, THE BIG WEDDING is an uproarious romantic comedy about a charmingly modern family trying to survive a weekend wedding celebration that has the potential to become a full blown family fiasco. To the amusement of their adult children and friends, long divorced couple Don and Ellie Griffin (De Niro and Keaton) are once again forced to play the happy couple for the sake of their adopted son’s wedding after his ultra conservative biological mother unexpectedly decides to fly halfway across the world to attend. With all of the wedding guests looking on, the Griffins are hilariously forced to confront their past, present and future – and hopefully avoid killing each other in the process.

The Big Wedding hits theaters October 26th, 2012.
