I assume you have started all the correct daemons and modules on the
server (laptop):
rpc.statd
rpc.portmap
nfsd
nfsd.ko

(appropriate init scripts will depend on your distro)

and configured properly
/etc/hosts.allow:

portmap:192.168.0.0/255.255.255.0 127.0.0.1
lockd:192.168.0.0/255.255.255.0 127.0.0.1
statd:192.168.0.0/255.255.255.0 127.0.0.1
mountd:192.168.0.0/255.255.255.0 127.0.0.1
rquotad:192.168.0.0/255.255.255.0 127.0.0.1

/etc/hosts.deny:

portmap:ALL
lockd:All
mountd:ALL
statd:ALL
rquotad:ALL

/etc/hosts.equiv:

localhost

and your /etc/exports should look like:

/media/jjj/Movies
192.168.0.0/255.255.255.0(rw,no_subtree_check,root_squash)
127.0.0.1(no_subtree_check,sync)

(all one line).

The NFS client then needs daemons running:
rpc.statd
rpc.portmap

You can now mount with

sudo mount 192.168.0.155:/media/jjj/Movies /media/jjj

NOTE:
If /media/jjj/Movies is owned by root:root you may not be able to mount.
 chmod -R <your local user>:users /media/jjj/Movies

If you have a firewall running (iptables, etc), you will have to "poke a
hole" for nfs.

This is how I have it set up so my desktop can share a drive "data" with
any client on my internal network. No password required.
