Isla Fisher showed that she has no fear while filming on set in Miami on Tuesday.

The actress took a plunge into the water while wearing hardly anything at all.

Looking flawless and fit in a white bikini, the 37-year-old was spotted flailing in the water for the cameras, and then hoisted to safety onto the deck of a boat.

Before taking a dip, Isla looked calm and collected wrapped up in a fluffy white robe.

Her signature red locks have taken on a darker shade for her role in the yet-to-be-named movie, also featuring actor Mos Def.

Away from the water and lounging stomach-down on a poolside chair, Isla took on a different look.

The actress plays the role of Myrtle Wilson, the mistress of Tom Buchanan, in Baz Luhrmen’s remake of The Great Gatsby, set to hit theatres on May 10.

Prior to that, Isla stars in Now You See Me, an action thriller which sees FBI agents track a team of illusionists who work like Robin Hood by pulling off bank heists during their performances then dishing out the money to their audience, which premieres in theatres on March 15.
