This looks pretty darn funny. I googled all the male leads to see if it was believable that they were child hood or college age friends.
Renner and Hamm were both born in 71
Helms was born in 74
Jake Johnson was born in 78
And Buress was born in 84
Isla Fisher who seems to be the only female member of the gang was born in 76.
I find things like this fascinating because when I write or try to I always try to have actors/actresses in mind to see if they are age appropriate.
Anyway the movie looks fun. If it's based on a memoir of love to read it.
