The 45-year-old 'X-Men' star will sport a mullet for the science fiction blockbuster, which began shooting earlier this week in South Africa, reported Ace Showbiz.
"Day 1 on 'Chappie'! Vincent is born, rocking the mullet. Working with Neill Blomkamp in SA. This film is rad," Jackman wrote on his Instagram post.
'Chappie' will see Sharlto Copley reunite with his 'District 9' and 'Elysium' director Blomkamp to play a robot who, after being kidnapped at birth by two criminals, is adopted by a dysfunctional family.
Sigourney Weaver and 'Slumdog Millionaire' star Dev Patel also feature in the cast for 'Chappie', which is due to open in cinemas in March 2015.
