Julia Roberts has pledged to spread kindness by teaming with Omaze to help launch a t-shirt campaign to rase funds for PACER, an organization working to end bullying and enhance the quality of life for people with disabilities.

The rest of the cast of Julia’s new movie Wonder also chimed in for the cause.
