Lindsay Lohan makes an appearance in the new movie Underground Comedy 2010, and not only are there hilarious performances from Bobby Lee, Joanna Krupa and Michael Clarke Duncan, but we get to see the 24-year-old jailbird pose as Marilyn Monroe and go after the paparazzi with loaded guns!

Vince Offer (aka "The Shamwow Guy") wrote the flick, and we're guessing Lindsay absolutely loved the aforementioned scene, even if she had to wear her SCRAM bracelet while shooting it! Production was completed just days before Lindsay sent to the slammer, and check out the video above to see her stellar performance!
