Leonardo DiCaprio and Robert De Niro offer fans an opportunity to be in new movie: 'This is your chance'

Leonardo DiCaprio and Robert De Niro have offered fans a rare opportunity to join them on the set for their new film Killers of the Flower Moon.

The actors appeared alongside each other for an Instagram announcement on April 16 where they introduced the All in Challenge as a way to help vulnerable communities in need of support as the coronavirus sweeps America.

"We're accepting the All in Challenge," DiCaprio said in the Instagram video. "Laurene Jobs and I helped created America's Food Fund to make sure that every family in need got access to a meal at this critical time. Our most vulnerable communities need our support now more than ever."

"That's why we're asking you to help us go all in," DiCaprio said. "Bob and I are going to be in a film called Killers of the Flower Moon. If you've ever wondered what it was like to work with the great Martin Scorsese, this is your chance."

Coronavirus: What you need to know

How is coronavirus transmitted?

The human coronavirus is only spread from someone infected with COVID-19 to another. This occurs through close contact with an infected person through contaminated droplets spread by coughing or sneezing, or by contact with contaminated hands or surfaces.

What are the symptoms of someone infected with coronavirus?

Coronavirus patients may experience flu like symptoms such as a fever, cough, runny nose, or shortness of breath. In more severe cases, infection can cause pneumonia with severe acute respiratory distress.

What is the difference between COVID-19 and the flu?

The symptoms of COVID-19 and the flu are very similar, as they both can cause fever and respiratory issues.

Both infections are also transmitted the same way, via coughing or sneezing, or by contact with hands, surfaces or objects contaminated with the virus.

The speed of transmission and the severity of the infection are the key differences between COVID-19 and the flu.

The time from infection to the appearance of symptoms is typically shorter with the flu. However, there are higher proportions of severe and critical COVID-19 infections.
