actors/actresses whose work that you enjoy but find boring as talk show guests ?

[70s show watcher]

for example i like will smith and harrison ford as actors but i always find that when i see them on talk shows i find them very boring so i almost always avoid watching them when they make chat show apperances will smith is just too dull as a guest and harrison ford seems to ply himself with a few drinks before going out onstage and acts like a boorish loudmouth what actors /actresses do you try to avoid seeing on talk shows but that you like otherwise?
