Jen-An: My jokes made it into Horrible Bosses!

Jennifer Aniston loved that some of her ad-libbed lines made into Horrible Bosses 2.

The former Friends actress is back as randy Dr. Julia Harris in the comedy sequel to the 2011 original movie, once again teaming up with Jason Bateman, Charlie Day and Jason Sudeikis.

The movie is full of laugh-out-loud moments, with the cast adding their own lines, too. Watching the final cut was fun for Jennifer, as she got to see which of her quips made it.

"So many!" Jennifer laughed to Us Weekly magazine when asked if a lot of lines didn't make it. "We’d throw in a few and volley back and forth from take to take. When we saw it, it was sort of a fun surprise to see. 'Oh, they chose that line.' There were endless lines. Charlie and I also had a wonderful surveillance camera moment that ended up not being in the movie. I had to do it on top of him while his character was in a coma."

Since her days in Friends Jennifer has played a variety of roles, and has fast become the go-to rom-com actress. However, playing kinky dentist Julia is a character the 45-year-old has come to love.

"I have thought a lot about her while I’ve done other films since then. She’s a hard one to let go of. I didn’t get enough of her. It went too quick," she smiled.

Next up is serious drama Cake, in which Jennifer plays Claire Simmons, a woman who starts a dubious relationship with a widower while confronting fantastical hallucinations of his dead wife.

The movie has been tipped for Oscar success, with Jennifer admitting the part was a dream come true.

"It was an actor’s dream role. You just get to bring in all the tools, all the things we learned as students in our classes, and apply them — and then get down and dirty. I did extensive research. I gave myself six weeks to just disappear and connect with her," she revealed.
