Photon animation speed

I am sorry for my English. My question is,
In my screen i can see that slowing down the animation but other players can not see. What is my fault?

Animator anim;
int playerID;
void OnTriggerEnter(Collider other){
if(other.gameObject.CompareTag("LuckyBox")){
if(playerID==1){
GetComponent<PhotonView>().RPC("animSpeed",PhotonTargets.AllBuffered,null);
}
}
}
void Start () {
playerID = PhotonNetwork.player.ID;
anim =photonView.GetComponent<Animator>();
}
[PunRPC]
void animSpeed(){
anim.speed=0.5f;
}
