Disney+'s sprawling library will continue to grow next month. The streaming service's biggest addition in April is the early release of Pixar's Onward on April 3. The animated family flick only hit theaters on March 6 but is moving to streaming early due to the COVID-19 pandemic. The month will also be something of a royal affair as Meghan Markle lends her voice to Disney+'s new streaming documentary Elephant, which also premieres on April 3.
