Liev Schreiber had a good reason for missing Tuesday’s Los Angeles premiere of X-Men Origins: Wolverine: His 21-month-old son, Sasha, was sick, PEOPLE has learned exclusively.

Schreiber, who plays Sabretooth in the film, immediately flew from L.A. to New York to be with his partner, Naomi Watts, and their two children.

Sasha, who was hospitalized overnight for respiratory issues, was released Wednesday morning.

“Sasha got home today and is feeling much better after being hospitalized on Tuesday night with respiratory problems,” Schreiber’s rep Ina Treciokas tells PEOPLE.
