Eddie Murphy is returning to the big screen opposite Danny DeVito and Arnold Schwarzenegger in a sequel to the 1988 comedy classic, Twins.

The new film, Triplets, will feature Murphy as the third sibling joining the odd pair, this according to Schwarzenegger, who shared the news this week during South by Southwest.

The former governor also acknowledged the physical differences between the three of them, saying, “Funny thing that happens in the mixing of the sperm,” according to Page Six. 

Age will play a role as well, as Murphy is 56 while both DeVito and Schwarzenegger are in their early 70s.
