The Horrible Bosses trailer is finally out ... and after watching, it was definitely worth the wait!

Jennifer Aniston and Kevin Spacey play mean-spirited bosses who are being targeted by their unhappy employees. Rounding out the awesome cast ... a barely recognizable Colin Farrell, Jason Bateman, Modern Family's Julie Bowen and Jamie Foxx.

Horrible Bosses hits theaters July 8.
