Beware, companies who fake celebrity endorsements, for you may just face Danny and Tess Ocean, a.k.a. George Clooney and Julia Roberts.

Perez Hilton reports that the two A-listers of ‘Ocean’s 11′ have filed a joint lawsuit against audio-visual companies Digital Projection, Inc. and Beyond Audio for the use of “large photographs of Plaintiffs in Defendants’ advertising, marketing and promotions.”

Join plaintiffs George Clooney and Julia Roberts are asking for unspecified compensatory damages, treble damages, punitive damages, attorneys fees and an injunction against further use of their names or images.

This is not the first time a company attempted to fake celebrity endorsements. Last month, The Hollywood Reporter reported that Clint Eastwood filed a lawsuit against furniture company Evofurniture, website Inmod.com, and Indmod.com’s domain name owners Alan Finkelstein and Casey Choron last month. Evofurniture had used the ‘Dirty Harry’ star’s first and last names for their products without the permission of Clint Eastwood.

George Clooney and Julia Roberts are not sharing an attorney for their suit against Digital Projection, Inc. and Beyond Audio. However, sources believe they deliberately teamed up for their lawsuit as a warning to other companies planning to use the images and likeness of  Hollywood stars without their permission.
