The high-pressure, fast-moving world of filmmaking can be intensely stressful at the best of times, but even more so for a cast member who happens to be eating for two.
These 10 movies all starred actresses who either fell pregnant shortly before filming started, or only realised once principal photography had already begun.
In most cases, the production had to pivot and creatively concoct a way to hide the fast-growing baby bump, be it by employing body doubles or even resorting to cutting-edge visual effects trickery.
And in each film the illusion was sold perfectly, because 99% of audiences would never have even the faintest clue that these actresses were all with child while performing major roles that, more often not, were also part of colossal blockbuster productions.
But before we move onto the list proper, here's a quick shoutout to Greta Gerwig, who directed the entirety of the recent Best Picture Oscar nominee Little Women while expecting a baby. Not bad at all...
Stay at home dad who spends as much time teaching his kids the merits of Martin Scorsese as possible (against the missus' wishes).
