Despicable Me 3 introduces Gru's twin brother

New trailer of animated comedy film Despicable Me 3 gives a sneak peak of the character Gru's twin brother. While the first trailer highlights the film's villain Balthazar Bratt (voiced by Trey Parker), the new sneak peek hilariously reveals that Gru (voiced by Steve Carell) actually has a twin brother named Dru, reports aceshowbiz.com. The sneak peek is set to Dr. Dre's song 'What's the Difference' and begins with a butler telling Dru an important thing. "I really must have a word with you on behalf of your twin brother Dru," says the butler. Gru, who is shocked, replies,"Twin brother?!"

The teaser switches to a scene in which Gru is taking a flight to visit his brother and yelling, "I can't wait to meet my brother!" At the end, it is revealed that Dru lives in a huge mansion. The film's plot detail is still kept under wraps, but it may focus on a sibling rivalry as well as Gru and Lucy's (voiced by Kristen Wiig) attempts to capture Bratt. The first Despicable Me was released in 2010 followed by 2013's Despicable Me 2.
